Latex is derived from field latex and it is processed using centrifuge methods. It contains 60% of Dry Rubber Content (DRC). Types of latex are differentiated by varying the amount used of preserved ammonia used such as High Ammonia (HA) and Low Ammonia (LA/LATZ).
Styrene-butadiene rubber (SBR) is the largest-volume elastomer. The addition of styrene increases the strength and contributes to the good wear and bonding properties. It also often improves the compatibility with other materials in blends.
Ribbed Smoked Sheet Rubber is commonly known as RSS. It is made directly from latex which is treated and then made to coagulate. The coagulated latex sheets are then air dried or smoked in ovens.
SMR/ SVR/ STR/ SIR
Standard Malaysian Rubber (SMR), Standard Vietnam Rubber (SVR), Standard Thai Rubber (STR), Standard Indonesian Rubber (SIR)
A blanket crepe rubber produced from the dries films and lumps of rubber found in the tapping cups at the beginning of the next tapping.
Latex content having been developed as a powerful adhesive base, which offers the following special characteristics: Initial Adhesive Strength, High Bonding, High Shear Holding Strength, High Peel Strength, High Wet Tack, Good Creep Resistance, Good Thickening.
Iron Mill Scale
Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling or steel mills. Mill scale is composed of iron oxides mostly ferric and is bluish black in colour.
Materials left over from product manufacturing and consumption, such as parts of vehicles, building supplies, and surplus materials. Unlike waste, scrap has monetary value, especially recovered metals.
