Comply with industry standards
The preparation of DOW DNDB-7441 NT 7 linear low density polyethylene resin uses UNIPOL™process technology. This product is used in the field of hoses and pipe fittings, and is also used in the processing of sealing gaskets, spiral wound hoses and bellows. The product has good drafting performance, the melt is not easy to break, it also has low temperature toughness, uniform matte surface effect, and excellent deflection life. Compared with conventional high-pressure, low-density polyethylene resin with the same density, its modulus (stiffness) is 50% higher. This product is especially suitable for profile extrusion. This processing requires stress cracking resistance, flexural wear resistance and easy extrusion processing. It can also be used as a modifier and blended with soft copolymers, such as ethylene-ethyl acetate (EVA) and ethylene-ethyl acrylate (EAA), to improve rigidity.
- ASTM D 3350: step PE123110A
- Comply with the requirements of FDA Regulation 21 CFR 177.1520 (c) 3.1a
- EU, No 10/2011
- Please check the regulations for complete details.
