The physical and chemical properties of TPEE
  Thermoplastic polyester elastomer referred to as TPEE or COPE, is a class of linear block copolymers containing PBT (polybutylene terephthalate) polyester hard segment (crystalline phase) and aliphatic polyester or polyether (amorphous phase) soft segment. TPEE belongs to high-performance engineering grade elastomer, with high mechanical strength, good elasticity, impact resistance, creep resistance, cold resistance, bending fatigue resistance, oil resistance, chemical resistance and solvent erosion, etc., and has good processability, and can be filled, reinforced and alloyed modification, in automotive parts, hydraulic hoses, cables and wires, electronic and electrical appliances, industrial products, stationery, biological materials and other fields have been widely used. Solvent erosion and other advantages, has good processability, and can be filled, enhanced and alloyed modification, in automotive parts, hydraulic hoses, cables and wires, electronic appliances, industrial products, sports and cultural goods, biological materials and other fields have been widely used.

How to crack and delaminate TPE/TPR products?
  TPE|TPR products cracking is what happened?   Answer: mainly by three reasons to cause TPE products crack!   1、Cracking   Material by air, ozone oxidation, aging cracking caused by. Some low hardness, thin size of the sheet products (especially SBS substrate), the

Analysis of the causes of discoloration of TPE/TPR products
  Analysis of the causes of discoloration of TPE/TPR products   Influencing factor one.   The influence of tpe raw materials on discoloration   1, the material is contaminated.   2, high content of moisture and volatiles.   3, colorants, additives decomposition.   Influencing factor two.   The setting of the injection molding process in tpe plastic parts also affects the product discoloration   1, screw speed is too high, pre-molding back pressure is too large.   2, the barrel, nozzle temperature is too high.   3, the injection pressure is too high, too long, the injection speed is too fast to make the product discoloration   Analysis of the plastic ber.   First of all, TPE raw materials on the impact of discoloration, the first and third are easy to understand (colorants, additives degradation and decomposition, their own discoloration, will naturally lead to discoloration of TPE products), and the second to be experienced professionals to explain the interpretation of doubt.   As for the injection molding process setting, the three influencing factors may lead to excessive friction and shear force or high temperature of the material, resulting in the possibility of degradation and discoloration, and if colorants are added to the material, the decomposition of colorants may occur and lead to discoloration of the final TPE products.

TPE/TPR particle lumping and sticking main reason analysis.
  TPE/TPR particle lumping and sticking main reason analysis.   1. Granulation process problems. The granulation process, material cooling is not sufficient, at a higher temperature on the packaging for finished products, heat gathered in the bag, and the higher the ambient temperature, the material is more likely to spit oil lumps.

TPE/TPR transparent natural color material yellowing resistance anti-UV effect how to identify
  When it comes to yellowing resistance and UV resistance, first we must know that TPE is composed of those materials, as we all know, TPE material in the production process is a physical reaction process, rather than a chemical reaction process, he is made of polymer materials SEBS or SBS oil-filled blend, in the production process if you want to achieve the desired effect on the addition of the right amount of additives, in the TPE production process for SEBS / SBS such a base material requirements are quite high. SBS such a base material requirements are quite high.
