Limwell New Material Tech.
In 2013, Shanghai Limwell New Material Tech. Co., Ltd. started the operation in Shanghai, China,
Limwell is an export-oriented comprehensive company, dedicating efforts mainly on the manufacturing and trading of rubber
aidditives and tyre-specific materials.Our manufacturing base are at Shan-dong and Zhe-jiang provinces of China.In addition
to that, we have also built partnership with a number of China local plants to enrich our product family.
Our products includes processing additives, Anti-ozone waxes, masterbatches, resins, peroxides, flameretarders, and a wide
spectrum of other materials used in tyre and rubber products.With the belief in mind to provide both trusted product quality and
outstanding sales service, we have become the stable supplier for a great number of tyre and rubber products plants all around
the world.
We uphold the concept "quality goes first, in service we trust, human oriented and sustainable development", willing to be the
best fit partner on your way to success!
Our Plant
One of our plants is located in the Zheshang Science and Technology Park at Jiashan, Zhejiang. This plant is at the center of
prosperous Jiangsu-Zhejiang-Shanghai economic zone, and has achieved fast and sustainable growth since the establishment
due to strong market demand and our outstanding research and quality control capabilities.
This plant can provide high quality masterbatches, homoginizer, vulcanizer, scorch retarder and several other rubber processing
additives. In 2014,we passed the lS09001 and IS014001 Certification audit.In 2016,we passed the TS16949 Quality System
and OHSAS 18001 certification audit.
In the fast development procedure, we have also paid attention to operate in a sustainable and environment friendly manner,
strictly adhering to the national and local environment protection regulations.
