                                                                  Tongxin have been dedicated in researching and developing high standard prefabricated

                                                                  rubber running track ever since 2001.Tophink keeps improving the production formula to

                                                                  pursue the optimal products with high performance and ultimate and comfortable experience

                                                                  for athletes in competition and training.

                                                                  R&D Technical Team

                                                                  Tongxin’s professional technical team was strengthened by the join of Dr Chen Chen(CTO)  

                                                                  from 2008,which to make the whole team become the core competitiveness in Tongxin’s

                                                                  development and technical support.

                                                                  Team core members:

                                                                                               Chenmin Cai : Chemical Professor, Zhejiang University.

       Chen Chen: PhD, Material Chemistry, Binghamton University (NY)

                                                      The international standard testing Lab was set up from 2008 and up to now is fully equipped for international

                                                      standard test including shock absorption test, deformation test, QUV aging test, tensile strength test, abrasion

                                                      resistance test, friction test, rebound test, high temperature test, temperature test with advanced testing

                                                      equipments from Switzerland. The skilled and professional experts combined with the whole advanced Tongxin to be the only one company providing products in compliance with national standard and IAAF

                                                      standard ,DIN the German standard.

                                                      As a whole, A closed-loop system of the prompt feedback from contractor, end-user, jobsite-installer are

                                                      transitioned to the R&D department and to factory accordingly was successfully built up. Under this system ,

                                                      the factory could keep pace with R&D team who develop production formula with reliable experimental data

                                                      analysis and timely improve the production technique, which make sure the products come out in the highest
