Applications

With good heat stability and low volatility under high temperature, good mould

release property and fluidity;PETS can be used as excellent lubricant in plastics and

rubber industry.Especially, it is suitable for the situation which requests high heat stability and good mould release.

It is alse one necessary ingredient for compounding Calcium-Zinc heat stabilizers,

functioning as the internal and external lubricants, comparing with other same lubricants, of better heat stability and low dosage.

It has the funciton of excellent nucleation for plastics which is part crystallization

and available in the transparent product.

When used as external lubricant of PC, hard PVC and other polymers.

The dosage of PETS is 0.1~1 percent, which is lower than traditional lubricant.
