Drying temperature and drying time of TPE materials

Water absorption of TPE materials is very small,about 0.3-0.5%.In the ordinary way Drying is not required under injection molding directly.For some products which need overmolding,you should need to dry it before Production and processing,such as after prolonged storage to achieve best results use on dry 2 hours at 70℃ .

Drying temperature and drying time of TPE materials:
TPE: hardness:30-60 shore(A),Drying temperature:60-70℃，drying time：1-2h.
TPE: hardness:70-100 shore(A),Drying temperature:70-80℃，drying time：1-2h.
The general principle of drying: higher hardness of TPE,higher Drying temperature,longer drying time.

Do you really understand the market of halogen free & flame retardant TPE

TPE (based on the SEBS substrate) conventional compound system, the flame retardant rating is HB (energy). However, with the expansion of the application field which has high demand for the performance of TPE. The emergence of flame retardant TPE, Let TPE can be used in the field of electronic materials, wire and cable field of Traditional technology by traditional processing.The key raw material is halogen for flame retardant , when you burn the halogen combustion,it will release of dioxin gas. cause tremendous pollution to enviroment. Some big company,like:apple, Dell, Sony, Samsung and other large enterprises are ban on using the materials including halogen.

In recent years, the research and development of halogen free and flame retardant TPE in China is in full swing, although a number of domestic TPE production enterprises have claimed that the halogen free flame retardant TPE material can be provided to used in the field of wire and cable.due to the pecial application of halogen free and flame retardant TPE,has high requirements on the formula and technique of TPE. Although all the TPE factory say that they can provide the halogen free and flame retardant TPE, just for the promotion.Only a few large companies can really provide the mature and stable products of flame retardant TPE.

TPE/TPR vs PVC in toy industry

The toy industry has been the important export industry in China. Soft plastic toys is always an active element in toy industry, such as: cartoon dolls, doll eraser, monster high fashion doll toys and the simulation toys and so on. They has been praised by foreign and domestic children.

But all the toy entrepreneurs feel that Export environmental safety inspection of toy industry is becoming more and more strict, Export inspection strict inevitably lead to the problems of production management and the rising cost of raw materials, so, toy companies only constantly digging and find the market demand, develop high value-added products so they can be in a better position to in the fierce competition of market.

At present most domestic enterprises usually use PVC soft rubber to produce toys. Due to most of PVC soft rubber contain toxic plasticizer(Phthalates), Foreign markets of children toys is reject PVC, and the European Union(EN71) and the the United States standard(ASTMF963) which also limits the application of PVC in the toy industry.

Soft TPE/TPR material is based on SEBS, SBS.TPE, TPR soft rubber material has been recognized by more and more foreign company because they contains no plasticizer, halogen free environmental safety materials. What is more, most TPE/TPR manufacturers can provide the Environmental production test report.
