Product benefits

1.The molecular weight of raw gum is higher, and the content of vinyl is reduced, so that the silicone gum has fewer crosslinking points, less vulcanizing agent, lower yellowing degree, better surface appearance, and higher grade of product under the premise of maintaining strength;
2.Volatile matter control within 1%, the product smell is lower, can be used in high VOC requirement applications;
3.With high molecular weight gum and better wear resistance when applicated for plastics;
4.Molecular weight control range is stricter, so that the strength of products, hand feeling and other indicators more uniform.
5.High molecular weight raw gum, keeps non-stick, used for color master raw gum, vulcanizing agent raw gum with better handling.

Features

Insoluble in water, soluble in toluene and other organic solvents, its products have small compression deformation, excellent characteristics of resistance to saturated water vapor, flammable in case of fire or high heat.

Applications

1.Low vinyl content, high molecular weight, suitable for the color masterbatch raw gum, vulcanizing agent raw gum with excellent handling, non-stick performances;
2.Suitable for silicone masterbatch raw gum;
3.Low vinyl content, suitable for the manufacturing of low hardness silicone products;
4.Ultrahigh molecular weight, suitable for adding in plastic to improve wear resistance and processing performance.

Packages

25Kg / box, craft paper box with an inner PE bag.

Transport and Storage

Suggest to be stored in a cool, ventilated warehouse, keep away from fire and heat. The temperature of the warehouse is not more than 40℃, and seal well when packaging. It can contact with the air, avoid contact with strong acid, strong alkali, metal lead and other compounds. Careful handling when loading and unloading to prevent packaging and container from damage, transport as non-dangerous goods. The shelf life is 3 years. After the storage period, it can be re-inspected according to the provisions of this standard, and if meet the quality requirements, this product can still be used.
