Product Details

Luoyang Gaoming New Materials Co., Ltd.

Luoyang Gaoming New Materials Co., Ltd. was established in 1998 and got its current name in 2009. Since its initiation, we have always followed the principles of product-oriented , quality-based and technological R&D-focused. We energetically promote our brand strategy and gear Gaoming brand to both domestic and international markets. After almost two decades of development, Gaoming New Materials Co., Ltd. has become a modernized large-scale business that focuses on macromolecular compound R&D and production with 3 branch factories.

Raw Materials

Well-selected Raw Materials.

The quality control of raw materials is fundamental to every aspect of the production processes. We have been working well with carefully-selected raw materials providers from overseas and put every effort in the raw materials storage procedure to make sure that impurities are fully controlled and prevented from the source.

Product Description

High-Quality & Widely-Used

This product is typically designed as cross - linkable

polyethylene insulation plastic particles.The process of

plasticizing granulation is carried out in a closed

system by employing premium polyethylene resins,high

quality cross-linking agents and other antioxidants. A

series of special loss-in-weight feeders also guarantees

the stable and precise outcomes . The excellent grafting

reaction ensures prominent extrusion ability as well as

stable and reliable insulating performance.

Application

* Maximum working temperature 90 ℃.
* 35kV cross-linked cable insulation compound.
