Model: ML2000
Appearance: white particles
Starting temperature: 140
Decomposition temperature: 145-220
Effective content: 58%
ML-2000 for a good dispersion of the composite foaming agent, non-toxic, tasteless, non polluting
. After the heat expansion microspheres in the formation of foam, has good foamability and of soft foam products
Resilience, widely used in various thermoplastic elastomers. The expansion and foaming of the microspheres at high temperature
Uniform fine products, excellent resilience, high gas. Excellent dispersion effect.
Applicable process: injection molding / extrusion process, the resin masterbatch and foaming agent are mixed evenly straight
Joint processing
Application areas: EVA, EBA, TPE (SEBS, SBS), TPO, TPU, TPV, PE (HD),
LD, MD), PP, PS. Foam soles; sealing strips (automotive, etc.); other packaging needs
Foaming area.
Recommended dosage: 0.8 to 3% injection, extrusion from 0.5 to 3%.
Process requirements:
1 injection molding
In most cases the ML-2000 foaming agent can be used in a general injection molding machine. Best
Using a nozzle with a needle valve, allowing the expansion of the model to fill.
In the product: to eliminate the depression; removal of warpage, improve dimensional stability, reduce weight, increase
The resilience of heated plastic elastomer.
In the process of high speed injection pressure, injection pressure is lower and lower die locking force drop
Low back pressure, reduced cooling time and increased yield.
?
2 extrusion molding
ML-2000 blowing agent can be used on most of the extrusion equipment. The screw length diameter ratio is 25-36D
The melting temperature is helpful to make the foaming agent completely decomposed
The gas can be avoided by the pores, and the utility model has the advantages of low shear screw and high rotating speed
To a large extent to reduce the destruction of blowing agent.
In the product: the product can be made into micro bubble structure; weight reduction of 20-50%; improve thermal insulation
nature
Application: pipe edge extrusion (wire casing, oil pipe, window edge); extrusion plate;
Packing: 20kg/ barrels, cardboard barrels packaging
