Description

LOTADER® 3210 is a random ethylene-butyl acrylate-maleic anhydride terpolymer (EMAMAH).
LOTADER® 3210 is a versatile adhesive for extrusion coating or lamination, designed as:
• Concentrate to be used in dry blend with LDPE. LOTADER® 3210 improves adhesion of LDPE on aluminum foils, metalized or primer-treated films.

• Ready for use resin to be used pure. LOTADER® 3210 gives excellent adhesion on substrates like aluminum foil, metallized plastics, paper, board, PE and some plastic films like BOPP.

• Coextrusion tie layer for PE/PA in extrusion coating process.

LOTADER® 3210 is also a coupling agent for mineral filled compounds such as halogen free flame-retardant wires and cables, a compatibilizer for polyamide/polyolefin blends and a modifier for polyamides.

Processing

As a result of high-pressure polymerization in autoclave reactor, LOTADER® 3210 molecular structure and rheology are remarkably suitable for all kinds of extrusion, including extrusion coating/lamination: low neck-in, excellent melt stability and drawability. Standard polyolefin extrusion equipment can be used for LOTADER® 3210, which has the same processability as LDPE and the same heat stability given by acrylate comonomers.
Recommended temperature range is from 270°C up to 320 – 330°C. It is recommended to purge the equipment with LDPE after a run is completed before shutting down.

Storage, Handling & Safety

LOTADER® 3210 is usually packed in waterproof bags or rigid containers with waterproof liner.
It should be stored in a ventilated area, away from heat, humidity and direct sunlight. Improper storage conditions may cause degradation and could have consequences on physical properties of the product.
It is recommended to reseal the bag or the liner after use to protect LOTADER® 3210 against moisture. Safety data sheet as well as information on handling and storage of the LOTADER® 3210 is available upon request to your SK Functional Polymer representative.
