Description:
The ultra-high bar has excellent wear resistance, good low temperature impact resistance, self-lubricating, non-toxic, water-resistant and chemical-resistant. Very high mechanical properties. It has outstanding impact resistance, stress crack resistance, high temperature creep resistance, low friction coefficient, self-lubrication, excellent chemical corrosion resistance, fatigue resistance, noise damping, nuclear radiation resistance. It can replace carbon steel, stainless steel, bronze and other materials for textile, papermaking, food machinery, transportation, medical treatment, coal mining, chemical industry and other industries.
UHMWPE Introduction:
Ultra-high molecular weight polyethylene (UHMW-PE) refers to linear polyethylene with an average molecular weight of more than 1.5 million. Due to its extremely high molecular weight (ordinary polyethylene is 20,000 to 300,000), UHMW-PE has unparalleled comprehensive performance compared with ordinary polyethylene and other engineering plastics:
- Extremely high wear resistance, 4 times higher than nylon 66 and PTFE, 6 times higher than carbon steel, the best among all synthetic resins at present.
- The impact strength is very high, which is 2 times that of polycarbonate and 5 times that of ABS, and can maintain high toughness at liquid nitrogen temperature (-196 ℃).
- Good self-lubricating property, its self-lubricating property is equivalent to that of PTFE, and the friction coefficient is only 0.07-0.11; it is only 1/4-1/3 of the friction coefficient of steel.
- The shock energy absorption value is the highest among all plastics, and the noise reduction effect is very good.
- It has high chemical stability and can resist various corrosive media and organic media within a certain temperature and concentration range.
- Strong anti-adhesion ability, second only to "Plastic King" PTFE.
- Completely hygienic and non-toxic, it can be used in contact with food and medicine.
- The density is the smallest among all engineering plastics, 56% lighter than PTFE and 22% lighter than polycarbonate; the density is 1/8 of steel, and so on.
Due to the above excellent comprehensive performance, UHMW-PE is called "amazing plastic" by European and American countries and has been valued and widely used in many industries.
Frequently Asked Questions (FAQ)
What is UHMWPE?
UHMWPE stands for Ultra-High Molecular Weight Polyethylene. It is a subset of the thermoplastic polyethylene with extremely long polymer chains, giving it unmatched durability, wear resistance, and impact strength compared to standard plastics.
What are the standard sizes available for the UHMWPE bars?
The standard diameter range is 15-200mm, and the standard length per piece is 1000mm. Custom dimensions can be configured to suit specific project specifications.
Can the colors and physical properties of the bars be customized?
Yes. While the standard colors are black and white, other custom colors are available. Additionally, special properties such as flame retardancy, antistatic behavior, high strength, and self-lubrication can be integrated.
Is UHMWPE safe for contact with food and pharmaceuticals?
Yes, UHMW-PE is completely hygienic, non-toxic, and meets regulatory standards for safe contact with both food and medical products.
How does UHMWPE compare to steel or bronze?
UHMWPE is significantly lighter (approximately 1/8 the density of steel), offers outstanding self-lubrication to reduce friction, and features excellent corrosion resistance and noise damping properties, making it an ideal cost-effective replacement.
