High purity Magnesium Hydroxide for Heat Shrinkable Tube

1.Introduction

Heat Shrink Tubing is a Special Polyolefin Heat Shrinkable Tubing which has high temperature shrinkage, soft flame retardant, insulation and anticorrosion function. It is widely applied to insulation protection of various wiring harnesses, solder joints and inductors, rust prevention and corrosion prevention of metal pipes and rods.
At present, the heat shrinkable tube widely divided into PVC heat shrink tube, flame retardant heat shrink tube, PET heat shrink tube. Magnesium hydroxide flame retardant have good flammability and chemical, coating modification magnesium hydroxide can ensure heat shrink tube’s physical such as tensile strength, longation, electrical.

4.FAQ

Q: What’s the magnesium hydroxide flame retardant mechanism?
A: Magnesium hydroxide is decomposed by heat to release crystalline water while absorbing a large amount of heat from the combustion zone, thereby inhibiting the temperature rise of the polymer material, delaying its thermal decomposition and reducing the burning rate.

Q: How do you ensure the quality of the product?
A: Top Chemical have a very complete quality management system, from the control of raw materials to the factory inspection of finished products. We regularly provide samples to third-party testing organizations for testing.

Q: How long is your delivery time?
A: We have 8 fully automatic production lines and can guarantee around it’ll use 15 days from the customer's order to delivery.
