Product description
The raw material is developed by Weihai Guangtong Plastic Products Co., Ltd (a paper proof enterprise of the State Grid) jointly with Beijing University of Chemical Technology, open the bag and use, without adding color masterbatch, directly produce the finished product, the quality of the national grid standard requirements.
The development of this modified raw material solves the problem that many MPP cable protection pipe enterprises' formula products can not meet the standard, while simplifying the production process, saving production time and improving production efficiency.
Ltd. can provide customers with a free 20-30 cm sample tube to do performance testing, while providing experimental pipe at low prices, after meeting the standard, the two sides then discuss the demand for modified material quantity and price. The modified material is divided into thin-walled, medium-walled and thick-walled materials. We guarantee the quality and delivery on delivery.
Welcome to contact us, and we look forward to cooperating with you successfully.
