Vinyl Chloride and Vinyl Acetate Copolymers MLC-20
Vinyl Chloride and Vinyl Acetate Copolymers
Vinyl Resin, Vinyl Acetate Copolymers Resins, Vinyl Acetate Copolymers Resins
Grade MLC-20: It is white powder,ketone and ester soluble with colorless, transparent solution, and it offers a desirable balance of chemical resistance, solubility, diaphaneity, film strength, and thermoplasticity. It has excellent interbedded adhesion. The film with high toughness,flexibility and lasting,anti-wear water resistance,low water swelling and low permeability of its lower melt index, It also has well sealing property in low temperature.

Application:
MLC-20 grade is used primarily for maintenance coatings,plastic coatings, heat-transfer paint,outdoor printing ink, carbon ribbon,adhesive for magnetic card and card board. When using with carboxyl resin in the heat sealing lacquer for aluminum foil and PVC can effectively reduce the heat sealing temperature, raise the heat sealing strength.
Package, storage and transportation:
* In kraft bag, lined with pp bags of 25kgs net, with PE inner bag.
* Store in a dry and ventilated place, do not place in open-air, avoid storage in direct sunlight and caution against wet.
* Must be transported in clean vehicle with awning and keep away from moisture.
