Chemical Additives for Non-crosslinked PE(NPE/EPE) & Crosslinked PE(XPE/XLPE) Foam Production

Chemical additives for Non-crosslinked PE (NPE/EPE) foam production

Non-Crosslinked PE Foam Extrusion

 

» Surface Active Agent (GMS, GLYCERINE MONOSTEARATE)

Anti-shrinkage agent to make light and resilient EPE foam

Grade Input quantity Features
GMS98
(Powder)		 1~2%

 · The best surface active agent for EPE foam production

 · Specialized formula only for EPE foam extrusion

 · Antistatic characteristics

 · Less shrinkage in thickness, width and length of EPE foam after extrusion

 · Higher purity

 · Not crispy but softer foam to be acquired
GMS9850
(Pellet/Granule)
Patent product		 1.6~1.8%

· Lighter but softer, more resilient and stronger foam to be achieved
 
· Aging time can be reduced in half

 · Input amount is constant and can be reduced in half

 · Foam surface is not oily because it disperses very well, penetrate into foam evenly without being left on the foam surface and do not make any mark so strong lamination with film/foil to be achieved.

 

» Talc Master Batch

The best nucleating agent to guarantee fine cells of EPE foam

Grade Input quantity Features
Talc M/B
(Standard)		 1~1.2% To make uniform, finer, and more consistent cell structure
TM-03
(Patent product)		 0.1~0.3% TM-03 provides excellent resilience with much finer cells & numerous cells by its good dispersion rateProduction cost is saved a lot by very small dosing quantity.

 

» Fire Retardant Master Batch (FR M/B)

     · To make EPE foam perfect fire retardant

 

» Heat Resistant Master Batch (HR M/B)

     · To stand high temperature upto 110’C

     · The better heat-resisting property than XPE foam to be achieved

     · Very resilient

     · The better FR performance like rubber foam

 

» UV Protective Resin (UV M/B)

     · To make foam strong against UV after application outside of building

FAQ

1. What is the difference between GMS98 and GMS9850?

GMS98 is a powder-type additive that is dosed during the heating of raw materials through a GMS pump. Since it is injected in the middle of the extruder, marks or migration may occur on the foam surface, which can cause staining issues.

GMS9850, on the other hand, is a granule or pellet-type additive and is a patented product of Pacific Industry. It is designed to achieve shorter aging time and improved foam resilience. GMS9850 is pre-mixed with LDPE resin using a screw mixer and dispersed evenly, preventing any surface marks or migration. As a result, automotive parts remain free from GMS staining.

2. What is the difference and advantage between Talc M/B and TM-03?

The standard dosing quantity of Talc M/B is approximately 1.0–1.2%, whereas TM-03 requires only 0.1–0.3%.

TM-03 is a patented product that enables the production of foam with excellent resilience and much finer cell structure using a significantly smaller dosing quantity, resulting in higher efficiency and improved foam quality.
