What is reprocessed UHMW?

What is reprocessed UHMW?

Reprocessed UHMW (Ultra High Molecular Weight Polyethylene) is a machinable thermoplastic that serves as an economical and environmentally friendly option for non-food applications. Reprocessed UHMW is made with a blend of virgin and recycled UHMW.

Can you thermoform UHMW?

UHMW-PE cannot be transformed and molded by conventional plastic processing techniques (injection molding, blow molding or thermoforming).

What is the difference between UHMW and Uhmwpe?

The key difference between UHMW and HDPE is that UHMW contains long polymer chains with very high molecular weights whereas HDPE has a high strength-to-density ratio. UHMW stands for Ultra High Molecular Weight polyethylene. It is also denoted by UHMWPE. The term HDPE stands for High Density Polyethylene.

Is UHMW easy to machine?

Is UHMW machinable? Ultra-High-Molecular-Weight Polyethylene (UHMW) is a great material for machining. A hard plastic with a slippery surface, it is resistant to abrasion and wear, and allows for an extended equipment life which helps cut maintenance costs.

What is PE sheet?

Polyethylene sheeting is a plastic film made from petroleum. It is used in construction as vapor retarders, window films, flooring and counter top protection, and even in roofing. Polyethylene sheet can be used to seal off rooms, cover building materials, and be used in lead abatement projects.

What is black UHMW?

UHMW (Ultra High Molecular Weight Polyethylene) is a common machinable plastic known for durability, versatility and cost-effectiveness as well as abrasion, impact and chemical resistances. The standard color of reprocessed UHMW is black, but also comes in green.

Is UHMW stronger than steel?

UHMWPE consists of extremely long chains of polyethylene (PE). This means that UHMWPE fibres has an incredibly high tensile strength compared to many other thermoplastics, and this also means that the material is much stronger than steel in the fibre direction.

Does UHMW swell?

Water absorption rate of UHMW is almost zero, therefore its strength does not deteriorate due to swelling caused by water absorption.

Why is UHMWPE so strong?

UHMWPE is a type of polyolefin. It is made up of extremely long chains of polyethylene, which all align in the same direction. It derives its strength largely from the length of each individual molecule (chain).

Is UHMWPE stronger than HDPE?

UHMW also has excellent resistance to stress and cracking, and the material has a low coefficient of friction (UHMW is self-lubricating). HDPE (High Density Polyethylene) has a somewhat lower tensile strength than UHMW. It possesses excellent chemical resistance and low moisture absorption.

How flexible is UHMW?

Ultra High Molecular Weight (UHMW) polyethylene is a semi-crystalline polymer that offers good abrasion and impact resistance plus a low coefficient of friction. It’s flexible enough to excel in both wet and dry environments with good wear and service life.

Can you tap UHMW?

RE: Tapping UHMW? Yes.

What is the difference between reprocessed and standard UHMW?

Reprocessed UHMW is excellent for non-food applications and offers all the benefits of standard UHMW at a much more cost effective price. Reprocessed UHMW features the same low coefficient of friction as standard UHMW while also offering a slightly better wear resistance.

What color does UHMW come in?

The standard color of reprocessed UHMW is black, but also comes in green. There is some inherent stresses in the material so if you need tight tolerance parts you may want to consider a material such as acetal.

Why choose UHMW-PE plastic?

Curbell Plastics has been supplying plastic sheet, rod, tube, films, adhesives, sealants, and prototyping materials for over 65 years. UHMW-PE. (ultra high molecular weight polyethylene) Polyethylene is a low cost, chemically resistant plastic material that can be used for a wide variety of applications.

What is the standard diameter tolerance of the rods?

Standard diameter tolerance of the rods is ±10% This material can be machined and should not shrink due to the machining process. UHMW expands and contracts considerably with temperature change. Other materials are available if you need a lower coefficient of linear thermal expansion.
