Because of the consumption of petrochemical resources, the global environmental pressure is gradually increasing. For this reason, Sunplas has made great efforts for many years and successfully developed Thermoplastic Polyester Elastomer (TPEE) based on bio-based and regenerated raw materials.
The hard segment in the TPEE is the PBT which derived from regenerated PTA and bio-based BDO.
The soft segment in the TPEE is the PTMEG which derived from bio-based raw materials.

The ratio of hard segment to the soft one can be adjusted in many ways due to the need of different hardness of materials.
At present, our bio-based and regenerated TPEE has been commercialized,and we named it as "BR-TPEE” according to its characteristics of "Biobased" and "regenerated".
For example the hardness of 25 shore D BR-TPEE we made ,the bio-based components can reach above 60% and with more than 30% of regenerated materials.
And the hardness of 70 shore D BR-TPEE we made ,the bio-based components can reach above 30% and with more than 60% of regenerated materials.

Sunplas can customize BR-TPEE to meet the environmental protection requirements of various countries and industries according to the specific needs of customers for bio-based and regenerated materials. The BR-TPEE has excellent performance and can be processedby injection, extrusion,,blow molding and other methods.

     Sichuan Sunshine Plastics Co., Ltd. (abbreviated as SUNPLAS) is the professional manufacturer of thermoplastic elastomer in China. Our Quality Management System has obtained the certification of ISO9001: 2015 ，also obtained the certification of Automotive Quality Management System Standard IATF16949.. All our products are made under the supervision of the National Engineering Technology Research Institute of Engineering Plastics for Stress Structure. After more than 23 years' practice, SUNPLAS can offer products with equivalent quality and properties of the sorts in the world, which have been widely used in the enterprises of automotive and electronic industries.

Our main product is thermoplastic polyether-ester elastomer(also named as TPEE or TPC-E or TEEE)。SUNPLAS manufacture and export TPEE（under EXW/FOB/CIF/CPT ... term），we also offer special use TPEE customization and solutions.

Thermoplastic polyether-ester elastomer are block copolymers consisting of a hard segment of polyester and a soft segment based on polyether or polyester.among which, polyether soft segment and non crystalline polyester comprise amorphous phase while polyester hard segment partly crystallizes to form crystal domain as physical crosslink point.TPEE combines the desirable elasticity of rubber and the strength of engineering plastics. Compared with rubber, it shows better processing properties and longer service life. The soft segment endows elasticity for TPEE and makes it act like rubber while the hard segment endows processing properties to make it just like plastics. In contrast to engineering plastics, TPEE exhibits same good strength but better flexibility and dynamic mechanical properties.

2 factories with 12000T/year capacity support short the production cycle and lead-time；internal R&D and inspect department cooperate with the independent inspect institute to make sure excellent quality and properties ；Talented material experts can customize TPEE according to the performance and properties specified by customers。

10+ years export experience with professional delivery forwarders enable SUNPLAS to organize fast and efficient delivery scheme for all over the world customers 。
