Polycaprolactone raw material

Hot Melt Adhesive Grade Polycaprolactone

Hot melt adhesive grade polycaprolactone is a kind of polyester polymer material, suitable for the production process of reactive moisture curing hot melt adhesive (PUR), and also suitable for the production process of physical curing hot melt adhesive, without inorganic powder and other auxiliary materials.

NOTICE: it can be used to package and make a variety of products,such as kraft paper bags,cold (hot) drinks cups

Coated Grade PLA

product introduction

PCL is a semi-crystalline material with low melting temperature, low activation energy for making hot melt adhesives, low melt viscosity, relatively low melt surface tension, strong penetration, and good toughness after curing, which is beneficial to textile fabrics, leather, Bonding of wood, etc. The hydroxyl group on the molecular weight chain segment of the hot melt adhesive grade polycaprolactone can react with the isocyanate group to form a firm chemical bond, which is especially suitable for reactive moisture curing hot melt adhesive system.

Product grade:

●eSUN400C

●eSUN500C

SPECIFICATION

Product Model	Appearance	Molecular Weight	Melt Index (g/10min)	Application
eSUN400C	White Pellet	40000	100-150	Hot melt adhesive, Masterbatch
eSUN500C	White Pellet	50000	30-50	Hot melt adhesive, Masterbatch

Properties

Low activation energy

Low melting temperature, low melt viscosity compared to other materials such as TPU.
Excellent initial tack

To give hot melt adhesives better initial tack strength, reduce the problem of adhesives due to low initial tack, especially suitable for PUR systems.
Good compatibility

Good compatibility with conventional polyester (including polyester polyol) and polyurethane materials, and can be used in combination.
Excellent toughness

Broaden the low temperature application range of the adhesive, especially improve the toughness of the adhesive under low temperature conditions.
Shape memory function

It is especially suitable for Gangbao hot melt adhesive for the front support and heel of shoes, which maintains memory support and enhances comfort.

Application Examples:

Application: Hot-melt adhesives for shoes (counter), interlayer adhesives for scattering coatings, moisture-curable hot-melt adhesives for textiles and woodworking, etc.

Features: Eco-friendly, biodegradable, compostable
