Total Energies Polypropylene 7232
PP(聚丙烯)
道达尔能源(Total Energies)
产品描述
Polypropylene 7232 offers excellent impact strength, clarity and gloss. The outstanding parison strength of 7232 allows for large container sizes and higher blow up ratios.
High Purity: 7232 features minimum taste and odor and optimum thermal stability for superior color and processability.
FDA: 7232 complies with all applicable FDA regulations and may be used under these provisions for food contact and packaging.
Recommended Applications: 7232 is ideal for both injection and extrusion blow molded containers for food, drug, cosmetic and toiletry applications requiring superior impact, strength and clarity.
Processing: 7232 resin processes on conventional blow molding equipment with typical melt temperatures of 390°F-450°F (177°C-232°C).
