The application of UHMWPE material is introduced

In recent years, UHMWPE has been widely used in board, profile, pipe and other main fields.Market research shows that UHMWPE has become a widely used industrial raw material with its excellent abrasion resistance, which is widely used in coal mining, shipbuilding, floor MATS and other occasions and products. These products need certain processing technology, the use of some equipment: for example, UHMWPE/PTFE tube extrusion machine, Polymer/Teflon bar extrusion machine, molding machine, Polymer PTFE sintering furnace, PTFE Gaskets Press moulding machine, etc. In recent years, China's demand for this product is increasing day by day.

UHMWPE separator is basically used in automobile battery manufacturing industry in developed countries in Europe and America.UHMWPE can also be used for viaduct as underrail spacer. UHMWPE film is based on UHMWPE board, which is a film with a thickness of less than 1 mm after cutting.Ninety percent of UHMWPE's customers are electronics floor mat manufacturers, and up to 95 percent of them are used for mouse floor MATS.There are some differences in the use of UHMWPE fiber between Europe and America and Japan. It is mainly used for body armor and weapons and equipment, accounting for 60% ~ 70% of the total consumption, followed by cables, fishing nets and labor protection supplies.Japan is mainly used for cables, fishing nets and labor protection equipment.

Compared with teflon (teflon) used in traditional mouse pad, UHMWPE film is more wear-resistant, and its self-lubricity is second only to teflon material.Cost, UHMWPE film density is small, according to square conversion UHMWPE film than fluron 50% lower.Therefore, UHMWPE film has gradually replaced teflon as the preferred raw material for floor MATS in OEM factories.

The application of UHMWPE

The molecular chain length of UHMWPE is 10 ~ 20 times that of hdpe. The main advantages of longer molecular chains (higher molecular weight) give UHMWPE are toughness, wear resistance and resistance to stress cracking. Because it is a kind of polyethylene, UHMWPE also has lubricity, chemical resistance and general purpose HDPE excellent electrical properties.

Long molecular chains make materials difficult to process in common moulding and extrusion equipment. When heated above the melting point, UHMWPE becomes transparent but does not flow.Chemical and performance UHMWPE is produced by ziegler polymerization. The process requires a particularly high degree of purity, ethylene monomer impurity control in a few parts per million. The product is a white powder with a particle size similar to that of table salt.

UHMWPE is used for low speed bearing housing. Low friction coefficient is further reduced by adding siloxane, aluminum disulfide, graphite and special paraffin wax. In the food processing industry, UHMWPE self-lubricity, easy purification, low flavor gas/flavor transmission and boiling water resistance are used. Has met FDA and USDA requirements for use in food, water, and pharmaceutical industries. Some of the USES of UHMWPE are based on its noise absorption and shock absorption. If UHMWPE is needed, dye can be used for coloring, while pigments are slightly inferior. PTFE/Polymer/UHMWPE Tube Ram Extruder, PTFE/Polymer/UHMWPE Rad Ram Extruder, Gasket machine, Plastic Pipe machine, etc. These machines can be used to produce a variety of fields need some ptfe, polymer, ultra high molecular weight and other products.

UHMWPE may be used in a new generation of self-unloading ore carriers, railway wagons and large trucks due to its smooth, non-viscous and abrasion resistance. These properties make it also useful for agriculture and earth-moving machinery, with UHMWPE materials to protect steel. The combination of chemical resistance and surface smoothness has many applications. For food processing industry, UHMWPE is used as the surface material of meat cutting board. UHMWPE is used as contact surface and roller for processing food and medicine conveyors. It has the properties of self-lubricating, resistance to boiling water and resistance to chemical cleaner.

It is regarded as an amazing material, and the new material will grow fast and be widely used.

UHMWPE Roller Features

1、Abrasion resistance and long life
The shell is made from UHMWPE which has abrasion resistance 10 times that of HDPE and 7 times that of steel. UHMWPE roller
have been subjected to continuous abrasion in very extreme quarrying, coastal and industrial applications.

2、Impact resistance and Impact energy absorbing
UHMWPE has the highest impact strength of any engineering plastics, about three times which of nylon, two times that of PC, five times that of ABS, withstands repeated impaction, even at -196 it is tough, together with its superior abrasion and corrosion resistance. UHMW-PE has made itself ideally suited for industrial applications in complicate and rough environments.

3、Effective sealing system
The primary labyrinth seal prevents most of the dust to get into the bearing house, and no water could leak in. The narrow
clearance between bearing house and shaft forms the second sealing, the bearing house are made of UHMWPE which has a
very low surface energy and are anti-adhesion, so it is repulsive to dust and water. It is quite difficulty for dust to get through the
narrow channel

4、Light weight and energy saving
UHMWPE rollers are only one third less in weight than steel roller, they are even lighter than HDPE roller, since they have
superior strength .Light weight and low friction result in considerable energy saving.

5、Reduced belt damage
UHMWPE shell is self-lubricant, and prevent the adhesion of any transfer material, so no damage was caused to conveyor belt,
even in case of roller be stopped.

6、Noise reduction
UHMWPE is a much better noise debase material than HDPE, UHMWPE rollers generate much less noise than conventional
steel roller, they are environmentally friendly

7、Corrosion resistance
UHMWPE roller can withstand humidity, corrosive chemicals, acids, salt and alkalis.

8、No sticking
UHMWPE could not be sticked by any material, so no conveyor material will be sticked to roller surface.

9、Machined face
Machined face of shell yield excellent balance and low T.I.R.10.Low maintenance fee Light weight make it easy to fit and install.
The labyrinth cap could be put back easily for clearing dust on line without take off the roller.

UHMWPE Rod

UHMWPE rod is an amazing engineering plastic which can solve many problems that other engineering plastics cannot. UHMWPE Rod is not as well-known as other plastics but is still highly important and has clear advantages over other more common engineering plastics.

Because UHMWPE rod has excellent abrasion resistance it is often used for sand, gravel or aggregate process applications. These environments are incredibly harsh on any bearing material but UHMWPE is one of the few engineering plastics capable of withstanding such punishing abuse.

 

UHMWPE Rod can also be used for low friction pulleys because of its very low co-efficient provides a bearing medium that is very free running and exceptionally long lasting. It is often found in food production environments where high volumes of containers need to be guided along conveyors or production lines. Because it has very low moisture absorption, it is also found in some high demand areas of marine applications. It’s sometimes used in some cryogenic components due to its low operating temperature abilities.

 

Because of its resistance to wear and impact, UHMWPE continues to find increasing industrial applications, including the automotive and bottling sectors. Since the 1960s, it has also been the most commonly used material for total joint arthroplasty in orthopaedic and spine implants.

 

Application for UHMWPE Rod:

 

• UHMWPE rod is usually chosen for it's low co-efficient of friction and so means it will produce bearings, bushes or pulleys that are highly free running, low friction and durable
• UHMWPE rod is also remarkably abrasive resistant. Therefore the UHMWPE rod can be used in high demand environments such as grit or gravel and have a longer life span when compared to other materials
• UHMWPE rod can often be used in high demand components in the food industry because it has a very low moisture absorption. UHMWPE rod has FDA approval and means that bearings etc. will not expand due to any moisture absorption
• UHMWPE rod is used in the marine industry for pulleys because of its low friction and minimal moisture absorption
