1. Hot melt adhesive production system

It can handle hot melt adhesive from 5000cps (higher) without having to add a melting cooler.

The low viscosity of the hot melt adhesive can be made by adding a melting cooler.

Hot melt adhesive range: a) based on EVA, b) polyamides, c) polyester,

D) amorphous olefin copolymer, e) all kinds of adhesives.

2. Commonly used elastomers:

Styrene thermoplastic elastomer (TPS), such as SBS, SIS, SEBS, SEPS, etc.

Polyolefin thermoplastic elastomer (TPO, TPE-O, or TEO): separate mixed S-TPO

Dynamic sulfur type TPV (PP/EPDM)

Ester thermoplastic elastomer (TPE),

Polyamide thermoplastic elastomer (TPA)

3, polyurethane thermoplastic elastomer (TPU)

Typical process:

1) reaction kettle, cooling, crushing, twin screw melting, underwater pelletizing, centrifugal dehydration system.

2) measurement, twin-screw reactive extrusion, underwater pelletizing, centrifugal dehydration system.

4. Polyolefin:

1) high output PE, PP production, (1000kg/h above)

2) high melting finger and high output PP production (above 300kg/h)

5. Blending modified materials:

1) general small particles: PE, PP, ABS Color Master batch, pigments and other additives + EVA+

2) filling modification: PP+80%-90% calcium carbonate production

3) blending modification: PE, PP, PS+SBS PP, PA+EPDM

4) glass fiber reinforced: PP, PBT, ABS, PA, PC, POM, PPS, PET+ length glass fiber / whisker powder coatings
