DOWLEX™ IP 41
HDPE
陶氏化学(Dow Chemical)
产品描述
DOWLEX™ IP 41 Polyethylene Resin is an Improved Processing high density resin designed to offer excellent processability and rigidity for food containers, overcaps and other general purpose applications.
DOWLEX IP 41 resin balances peak molecular weight with a proprietary, optimized molecular weight distribution and a slightly higher density for excellent rigidity. This resin has demonstrated excellent processability over a wide range of processing conditions.
