Popular Design for Paper Phenolic Rod - High Density Polyethylene (HDPE) – Shielday

High density polyethylene (HDPE) softening point for 125 ~ 135 ℃,
working temperature 100 ℃; 
Material features:
Heat & cold resistance, good abrasion resistance, high tensile strength, electrical insulation, good chemical stability, chemical corrosion resistance; low water absorption and permeability.
Wire by increasing HDPE outer coated layer can improve the flexibility, temperature resistance, chemical resistance and mechanical strength, breakdown voltage. Compared with the ordinary wire, outer coating wire can be insulated , high temp resistant, also the bending life of the wire is significantly improved. 
Advantages:
Insulation
High temperature / heating Resistance
Good flexibility
Stress resistance  
Resistance against oils   
Outer coating material, thickness of coating layer and concrete structure of inner conductive wire can be selected and combined in order to have best performance for various applications:
Inner conductive wire material, dia:
Structure: single ,multiple stranded or not stranded / twisting direction, twisting method
1) Singel / stranded wire: Bare copper, tin-plated, silver-plated, gold-plated, nickel-plated, bare copper alloy, tin copper alloy , silver copper alloy, stainless steel etc. 
Single wire Dia: 0.01~0.12mm
2) Metallized high strength yarn: above conductive wire covered aramid yarn inside which can bears the vertical tensile strength,be higher strength,more flexible, long life and temp resistance.   Yarn Dia: 0.05-0.3mm
Outer insulation coating: PTFE(Teflon), HDPE(High Density Polyethylene), textile outer etc
Outer Dia: 0.5 – 5.2 mm
Coating layer thickness: ≥0.15 mm
Applications:Smart Textiles ,RFID,Medical ,Heating Etc.
