Introduction        
A flame-retardant (except transparent) and adhesive-lined cross-linked polyolefin heat-shrinkable tube, which is very suitable for applications that require insulation, corrosion resistance and mechanical stress relief, including connectors, wiring harnesses, electronic components, etc.

 

Features        
Operating temperature: -40℃-110        
Minimum full shrinkage temperature: 125         
Shrink ratio: 3:1        
Environmental protection, RoHSELV compliant        
ColorBlack (standard), transparent, white, red, blue, yellow, green (non-standard)
