Rubber Vulcanizing agent: Insoluble Sulphur
 

1.IS-series
2.IS-HS Series(highly thermal stability )

It's scientific name is high polymer of sulphur ,the shorter form is IS .It contains different quantity of oil extension ,so forming Is-series oil extension and nonoil extension product,with the development of meridian tire industr,we have devloped the high temp stability (Is-Hs) series product.
Insoluble Sulphur is a new rubber vulcanizing agent,It can overcome many ordinary sulphur's shortcomings,but also can improve the quality of the rubber product.

Product advantage:
1.The rubber doesn't spout frost during storage time .It can keep the uniform function of the rubber material. It overcomes short coming of spouting frost cause the rubber's bad cohesion .And it prevents the pollution to the rubber product and the models.
2.It has no moving phenomenon between rubber layer, it protects the surfaces to form stickiness.
3.Reduce coking during the mix smelting and storage time.
4.Shorten vulcanization time ,reduce the consumption of sulphur, improve the rubber product's antioxidize propety.
5.Engance the rubber binding with oter materials'

The use of the product:The Is and Is-Hs- Series product apply widely to natural rubber and many kinds of synthetic rubber .They suit to tire and sealant of tape and pipes making ,especially to meridian tire's making.

Pakage and storage:
The product packed in PP plastic knitting bag ,lined with PE plastic bag.They shoule keep in vent and dry place in indoor temperature.The temperature cann't surpass 40 ,pay attention to fire prevention ,heat prevention ,dampproof, don't press to form lump.They can't be placed with basic,amine materials .The quality guarantee time is half a year.
