FeaturedPolyurethane Sheet in Mining & Aggregate Industry
How Cast PU Elastomer Outperforms Rubber in Screening and Wear Applications
Cast polyurethane sheets have become the material of choice for mining screen panels, conveyor liners, and hydrocyclone components. With 3–5× better abrasion resistance than natural rubber and superior oil resistance, PU delivers longer service life and lower total cost of ownership in demanding mining environments.
Technical GuideHow to Choose the Right Polyurethane Hardness (Shore A Guide)
Shore A 20 to Shore D 80 — Matching PU Hardness to Your Application
Selecting the correct hardness is the single most important decision when specifying cast polyurethane. Too soft and the part deforms under load; too hard and it loses impact absorption. This guide explains the Shore A and Shore D scales, typical hardness ranges for common applications, and how to specify the right grade for your project.
Material ComparisonPolyurethane vs. Natural Rubber: Which Should You Choose?
A Practical Comparison for Industrial Wear, Sealing, and Vibration Applications
Polyurethane and natural rubber are both elastomers, but they serve very different needs. PU offers superior abrasion resistance, oil resistance, and load-bearing capacity, while rubber excels in dynamic flex fatigue and low-temperature performance. This article compares the two materials across 10 key performance criteria to help you make the right choice.
Custom FabricationCustom Polyurethane Machined Parts & OEM Components
From Cast Blanks to Finished Wear Parts — Our Fabrication Capabilities
Beyond standard sheets and rods, Jiasheng Plastic offers full custom fabrication of polyurethane components — from CNC-machined bushings and rollers to molded screen panels with metal inserts. Our cast PU process allows precise control of hardness, color, and dimensions for OEM and replacement part applications.
Conveyor SystemsPolyurethane Components for Conveyor Systems
Impact Bars, Skirt Boards, Wear Strips, and Roller Covers in Cast PU
Conveyor systems in mining, bulk handling, and manufacturing rely on polyurethane for impact absorption, wear protection, and noise reduction. Cast PU impact bars absorb the energy of falling material at transfer points; PU skirt boards seal the conveyor edge; and PU roller covers provide grip and protect the belt. Learn how to specify each component correctly.
