shenzhen Erison high temperature FEP heat shrink tube

Heat shrink tube 1.Antilflaming, insulation, 2.High diaphaneity, 3.Material: 100% virgin FEP 4.high temperature for work

 

Product Description

FEP retains PTFE many kinds of characteristics basically, but with lower 50°C in the thermostable limit against PTFE. With low melt viscosity and outstanding thermo stability, FEP enable to produce with the method of extrusion, transmission, injection and compression and  the blow molding formation method like other hot plastic products.

The FEP molding is divided into the FEP hyaloids canal, the FEP heat shrink tube, the FEP membrane and so on.

1.     Application

Widely applies in aerospace and instruments and meters and light industry chemical industry, food medical service and electronic electric appliance and posts and telecommunications correspondence, petrochemical, metallurgy electron, railroad transportation and electrical machinery electric appliance, domestic electric appliances, high-rise construction, decorative lighting illumination, special transformer, special electric cable, sensor, thermal element and other industry.

2. Specialty

1. Shrinkage ratio  1.3:1

2. High flame retardant, wear and shearing resistance and has excellent resistance to chemicals corrosion ability

3. Non-harmful material to the environment like phenylate PBBEs, PBDEs including chlorine chemical compound PCBS, PCPS and multi-bromine biphenyl PBBs and multi-bromine oxidation biphenyl PBBOs and multi-bromines and so on and in the line with SGS environmental instructions.

3. Model

The min inside diameter can be Diameter1.5 atfer shrinking, and the max inside diameter can up to Diameter200 , wall thickness up to 0.1-2.5mm
