Explore for TPE, TPR castor formula problem

We all know that choice models in do castor has exquisite, now we are discussing TPR in play the role of have to wear? Compatibility? Recently see peer castor material on the market. The same is transparent material. From the density to test and found their density than us. We is 0. 9. They contain the TPR is 0. 99. Take to do the beta, abrasion test, our pure SEBS + PP formula is better than them wear formula 2 times. But the final sample, the customer chose the one low price. Want to ask next everybody below. TPR added in TPE castor hope to achieve high wear-resisting. Reasonable or unreasonable. The hard plastic castor industry is given priority to with the copolymerization PP, also some use of PA nylon, soft plastic use TPE, TPR accounts for a considerable proportion of the market demand. This kind of castor processing molding, usually adopts two-step injection molding. The first step to hard plastic injection molding pieces of PP or PA; The second step, in another set of mold, put good hard plastic forming parts, and fixed position, then RuanSu TPE, TPR shot stick to the position of the hard plastic parts need to be coated. About castor introduction 1, thermoplastic elastomer TPR TPE | TPR rubber is easy to processing molding, excellent wear resistance and elasticity, good vibration and low noise performance, become the important raw materials of casters and wheels. 2 wheels, usually casters, such as shelves, cart wheels is a hard plastic (such as Such as PP, PA) And RuanSu ( Such as TPR, TPE, PU, EVA, TPU) Composite forming. Hard plastic as skeleton materials of castor, have the effect of bearing, soft glue have non-slip, shock absorption and noise reduction. 3, at present, castor industry, hard plastic is given priority to with the copolymerization PP, also some use of PA nylon, soft plastic use TPE, TPR accounts for a considerable proportion of the market demand. This kind of castor processing molding, usually adopts two-step injection molding. The first step to hard plastic injection molding pieces of PP or PA; The second step, in another set of mold, put good hard plastic forming parts, and fixed position, then RuanSu TPE, TPR shot stick to the position of the hard plastic parts need to be coated. Castor embryo MianRuan rubber thickness is usually in 5 ~ 20 mm, and because the material has excellent wear resistance and flexibility ( This determines the material specific formula) , so the products of thickness and material of the formula determines the TPE, TPR coated temperature may be a thin layer and other coating products. We suggest that encapsulates the PP, package adhesive and temperature 180 ~ 220 ℃, shoot encapsulates the PA, requires a temperature of 240 ~ 280 ℃. Basic method: castor wheels industry test the performance of the product is generally under a certain load test MianRuan rubber wheels what rules mileage wheel tire wear and tear. About the TPE, TPR used in castor products of other related cases, such as toy wheels, have hollow TPR toy rubber wheels, solid TPR, TPE toy wheels, as well as some special curtain pulley and so on. The curtain pulley is usually adopt TPE, TPR plastic bags PA6 or POM. Thermoplastic elastomer TPE | TPR rubber is easy to processing molding, Available direct injection molding) , good abrasion resistance and flexibility, good vibration and low noise performance, become the important raw materials of casters and wheels.
