Product Description

PE500 material produced by GELAR is manufactured from high molecular weight polyethylene and has an identical friction coefficient to grade PE1000. Meanwhile, the wear resistance of PE500 is only one-third lower than that of PE1000, a difference that often goes unnoticed in real-world operating conditions since laboratory testing does not fully replicate actual application environments.

Product Advantage

Advantages and Properties

·Identical coefficient of friction to PE1000

·Wear resistance approximately one-third lower, but sufficient for most practical conditions

·High tensile strength and frost resistance

·Cost-effective compared to PE1000, PE2000, and PE9000

FAQ

FAQs

Can UHMWPE be used for abrasive wear protection (sandblasting)?
Require: A metal nozzle for cement mortar delivery needs to be protected against abrasion. Will a UHMWPE liner protect the nozzle from wear? Or should boron carbide be considered instead?

UHMWPE cannot be used for the specified purpose – rapid wear will occur. Few materials can match ceramics in terms of wear resistance.
Polyceramoplast composites are effective against adhesion/freezing and chemo-abrasive wear in mining equipment, where it is economically impractical to cover large areas with expensive ceramics and where the service life of ceramics would be excessive.
The above response mentioned milling or waterjet cutting. Is a manual milling machine or a wood electric planer suitable for chamfering?

Chamfering with hand tools is possible. The machining accuracy in this case depends on the operator’s skill.
How feasible is laser cutting of UHMWPE sheets of different thicknesses? What recommendations can you give for laser cutting?

Laser cutting is not used for UHMWPE: the laser fuses the edges, the material loses its properties in the cutting zone, and yellowing occurs. Milling or waterjet cutting is recommended.
What is the UV resistance?

On its own, without additives, UHMWPE is resistant to UV radiation and thermal oxidation (unlike HDPE/LDPE). With the addition of stabilizers, the resistance increases to a level that lasts for several decades.
Procedure for determining the product warranty period (regulations)?

As a rule, we provide a warranty that the material complies with the specifications in the TU (Technical Specifications) – including wear resistance, tensile strength, impact toughness, etc. – this can be regarded as the regulation and the main warranty aspect.
In individual cases, we provide a warranty for the operation of linings or products in specific units/mechanisms (e.g., turnkey buckets) – for up to 1 year. The decision is made based on a completed questionnaire.
