Recent devolpments on photoinitiated crosslinking of polyethylene and its applications for manufacturing insulated wire and cable

Baojun Qu; Wenbao Bao; Qianghua Wu; Wenfang Shi; Shujun Ma; Zhenshan Jia

Recent developments on photoinitiated crosslinking of polyethylene and its industrial application for manufacturing XLPE-insulated wire and cable have been reported in detail. This advanced technology is also very promising for photocrosslinking of halogen-free flame retardant polyolefins and EPDM rabber and their applications of related crosslinked wire and cable.

Photocrosslinking of intumescent halogen-free flame-retardant LLDPE/EVA/IFR blends

Baojun Qu; Wenbao Bao; Lei Ye; Qianghua Wu; Shujun Ma; Zhenshan Jia

Photocrosslinking of the halogen-free flame retardant linear low density polyethylene /poly(ethylene-co-vinyl acetate) (LLDPE/EVA) blends with the intumescent flame retardant (IFR) of phosphorous-nitrogen compound (NP) in the presence of photoinitiator and multifunctional crosslinker and the characterization of related properties have been investigated successfully. The results from the gel content and heat extension rate (HER) show that the LLDPE/EVA/IFR blends filled with NP are readily photocrosslinked by UV-irradiation of 5 s to obtain a gel content of above 75% and reach the HER value of about 50 %. The data from the LOI, UL-94, water-resistant, and mechanical measurements show that photocrosslinking can considerably enhance the mecnanical, flame retardant, and water-resistant properties of the LLDPE/EVA/NP samples.
