Product Description

Product Description

Polyceramoplast™ rods and bars are manufactured via the plunger extrusion (RAM-extrusion) method from ultra-high molecular weight polyethylene grades PE1000 and PE9000. This technology ensures high structural homogeneity and stable physico-mechanical properties throughout the entire length of the product.

Applications
Rods and bars are used for manufacturing parts through machining, including:Rollers,Bushings,Rings and other friction components .

 
Thanks to the combination of high strength, sliding properties, and stability at low temperatures, Polyceramoplast™ rods and bars are used in mechanical manufacturing, transportation, and equipment requiring high wear resistance and chemical inertness.

Company Profile

Shenyang Gelar Composite Materials Co., Ltd. is a joint venture invested by the Europe-based Gelar group, utilizing advanced European technologies and specializing in the R&D, production and sales of high-performance engineering plastics. As the manufacturing base of the European enterprise in China, we produce high-quality products by advanced production equipment, strict quality control system and continuous R&D capability. Our "polyceramoplast™"product series are composite materials manufactured from ultra-high-molecular-weight polyethylene (UHMWPE) and modified additives through modification technologies. Among them, the polyceramoplast™ α,β,γ series—polyceramic composites—benefit from unique production technology and specialized equipment, significantly enhancing the modified properties of UHMWPE to achieve superior wear resistance and anti-adhesion performance. 

Gelar aim to become a world-leading high-performance engineering plastics and composite materials manufacturer.

FAQ

Q1: Is it possible to use UHMWPE as protection against abrasive wear (sandblasting)? The task is to protect a metal cement slurry feed nozzle from abrasion. Will a UHMWPE liner help protect the nozzle from wear? Or should we look into boron carbide?

A1: For the stated purposes, using UHMWPE is not feasible—it will wear out quickly. Few materials can compare with ceramics in terms of wear resistance.

PolyCeramoplast composites are effective against adhesion/freezing and chemical-abrasive wear in mining equipment, where covering large areas with expensive ceramics is economically impractical and where the service life of ceramics would be excessive.

Q2: An answer was given above regarding cutting with a milling cutter or waterjet. Would a handheld router or an electric wood planer be suitable for chamfering

A2: Chamfering with manual tools is possible. The accuracy of the processing in this case depends on the skill of the operator.

Q3: How suitable is laser cutting for UHMWPE sheets of various thicknesses? What recommendations can you provide for laser cutting?

A3: Laser cutting is not used for UHMWPE: the laser melts the edges, causing the material to lose its properties in the cutting zone, and yellowing is observed. Milling or waterjet cutting is recommended.

Q4: What is its resistance to ultraviolet light?

A4: UHMWPE itself, without additives, is resistant to UV and thermal oxidation (unlike HDPE/LDPE). With the addition of stabilizers, its resistance increases to a level sufficient for several decades.

Q5: What is the procedure for setting the warranty period for products (policy)?

A5: Typically, we provide a warranty for the material's compliance with the technical specifications (wear resistance, tensile strength, impact toughness, etc.)—this can be considered the policy and the main aspect of the warranty.

In individual cases, we provide a warranty for the performance of the lining or product in a specific unit/mechanism (for example, a "turnkey" bucket)—for up to 1 year. The decision is made based on a completed questionnaire.
