Silicone masterbatch

Various substrates

Silicon polymer, in addition to the smoothness of other lubricants, can be added in a high proportion to remove surface oil.

Wax powder

PE, PP, PS, ABS, PA, PVC, etc.

It improves the affinity with inorganic substances and the compatibility of polar resins. It has stable chemical properties and good electrical properties. It is an effective dispersant in the production of masterbatch. It can effectively improve the vividness of the color of the product.

EBS

Thermoplastics include polyethylene, PVC, ABS, phenolic and aminoplasts

Used as an internal and external lubrication modifier in thermoplastic and thermoset plastics. It can be used as a release agent, anti-adhesive agent, antistatic agent and surface treatment agent in plastics and rubbers, which can improve the surface properties such as appearance, color and feel of the product, and improve the dispersibility of additives.

Slip agent and opening agent

PETS

PC

Improve smoothness and high cost performance

Special slip agent

For polyolefins such as PP PE and TPU

Solve the problem of demoulding, which can improve production efficiency

Reduce the scrap rate of secondary treatment (spray printing, etc.)

Improve product light sensitivity

Improve the dispersion of other fillers and reduce overall costs

For styrenics such as HIPS GPPS AS PS

For polyesters such as PC PET PBT PLA

For polyesters such as PC PET PBT PLA

Used in engineering plastics such as PA ABS POM

ER erucic acid

Olefins, PVC and other polymers

Improve substrate surface smoothness

Increase productivity

Improve filler dispersion

Improve the opening of film products

VRX oleic acid

Olefins, PVC and other polymers

Medium high mesh talcum powder

LLDPE

In the application of film modification, there is a synergistic effect of opening, reducing the overall cost

Thermodynamic performance additives

Toughening agent

MBS

PC, PC/PBT, PC/ABS, etc.
