Synthetic Rubber (CSM)

Synthetic Rubber (CSM)

  CSM is produced from polyethylene by chlorination and chlorosulphonation with chlorine and sulphur dioxide gas. Various types of CSM are obtained according to degree of chlorination and chlorosulphonation as well as sort of polyethylene polymer. 

  CSM has excellent resistance against ozone, weather, oil and chemicals. And it can be colored in brilliant shades.

CSM finds a wide application in:

1. Coatings for auto and industrial tubes, coal gas and petro-liquified gas tubes in daily life;

2. Cablessheathes, coatings, gaskets, rollers and linings of various industrial parts;

3. Life boat, life vest, over-clothes, handrails of elevator, etc., as a special elastomer;

4. The second generation of adhesive agent (SGA adhibitting agent);

5. Heat-resistant, grease-proof, and ozone-proof materials, and water-proof pressing and extending materials increasingly required year by year.

  CSMs different applications as per each grade:

1. CSM-20 finds a good application in coatings of soft materials and adhesive products, and the best one is of gum latex;

2. CSM-30 is primely applied in coatings of ebonite compounds, in addition to anti-corrosion coatings of inside and outside walls of plants and equipment  under acidic and alkali conditions, because of its anti weather and aging characteristics and acid-proof, alkali-proof and solvent-proof properties;

3. CSM-30 can be also used for medical gloves and electrical insulating gloves, etc.;

4. CSM-403304, 3305) is mainly applied in cablesinsulating sheathes and cablesjackets, surpassing CSM-20 in aspects of grease-proof, deformation-proof, anti-breaking, anti-abrasion and acid-proof;

5. CSM-45 is chiefly applied in making of high rigidity products, such as plastic carpet, waterproof roof, shoe sole and sponge insole.

  Properties:

  CSM is a white or yellowish elastomer with commonness of base polymers. It dissolves in aromatic hydrocarbons and chlorhydrocarbons, but not in alcohols and fatty hydrocarbons, while it swells only in ketone and ether.

  1. The performance of un-vulcanized CSM varies with the feed stock of grades, structures, recipes and reacting conditions of raw polyethylene and processes of CSM.
     
2. CSM being vulcanized, it will not affected by ozone, standing well against degradation of oxygen and other oxidants. In comparison with other elastomers, it shows a strong resistance to denting and tensile, high modulus and rigidity. It stands all square with other synthetic rubbers in anti mangling with characteristics of tear and abrasion-resistance and chapping-proof.
