Alkatuff® LL722 Qenos Polyethylene, Linear Low Density

Product Description

Alkatuff LL722 is a hexene LLDPE material specifically designed for rotational molding applications that require excellent ESCR, chemical resistance, stiffness and toughness. Alkatuff LL722 does not contain UV stabilizer.

Application:
Alkatuff LL722 is designed for chemical and water tanks and other applications where toughness and stiffness are important. For outdoor applications, an appropriate UV stabilization package should be added.

Specifications:
Alkatuff LL722 complies with the non UV base resin requirements of AS/NZS 4766 Polyethylene storage tanks for water and chemicals.

If this product is used for food contact applications, then the user needs to ensure compliance with the requirements of AS2070-1999 and relevant FDA regulations.

When used in accordance with FDA applications guidelines, this product meets the requirements of FDA 21 CFR 177.1520 (c) 3.1a and AS2070-1999 section 4.1.1(a).
