1. Product Introduction & Main Application
Arnico’s Polyethylene (PE) is the world’s most widely used thermoplastic, supplied as milky-white translucent granules, produced from the polymerization of ethylene gas under controlled pressure and temperature. This engineered polymer family includes High-Density (HDPE), Low-Density (LDPE), and Linear Low-Density (LLDPE) grades, which, due to their affordable price, chemical resistance, electrical insulation, and easy processability, are used in packaging, pipe manufacturing, tanks, and thousands of other products.

3. Features & Benefits
-
LLDPE Film: Excellent tensile strength and tear resistance in thin films, ideal for stretch and heavy-duty packaging.
-
HDPE Injection: High flowability and a fast cycle time for producing high-precision parts.
-
Exceptional Chemical Resistance: Inert to acids, bases, solvents, and moisture.
-
Hygienic & Food Safe (Food Grade): Odorless, tasteless, and has FDA and EFSA approvals for food contact.
4. Industrial Applications
-
Packaging: Shrink film, stretch film, freezer bags, and milk bottles.
-
Pipes & Fittings: Water and gas distribution pipes, and drip irrigation tape.
-
Consumer Goods: Buckets, fruit crates, toys, and household appliances.
-
Industrial Containers: Drums and tanks for chemical storage.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): The granules are inert, but dust is an irritant. Vapors are released at processing temperatures. The Arnico MSDS file must be obtained.
-
Storage Conditions: Store in 25kg bags or big bags in a dry, cool warehouse, away from direct light and heat.
-
Personal Protective Equipment (PPE): Gloves for handling hot product.
6. Quality Assurance & COA
Arnico PE shipments are accompanied by a specialized Certificate of Analysis (COA) detailing the MFI, density, and mechanical properties.
