Marlex® 7120X
LLDPE
雪佛龙菲利普斯(Chevron Phillips)
产品描述
This linear low density polyethylene is an ethylene-hexene copolymer tailored for film applications that require:
• Excellent processing characteristics
• Exceptional drawdown
• Use alone or in coextrusions; blends with other polyolefins
Typical blown film applications include:
• Coextrusions
• Blend component to improve drawdown
• Thin gauge applications
• General purpose packaging
