Rubber Products:
The HML range of Natural Rubber grades finds
extensive usage across a wide spectrum of applications, ranging from
manufacturing industry and transportation to health care and daily life. In
Industry, rubber is used for V belts, conveyor belts, transmission belts,
bushes etc., where as in transportation, rubber has a more significant role in
the form of automotive tyres and tubes, brake seals. Gloves, tubes, catheters,
condoms etc. are the major rubber products used in the field of health care.
Rubber is also an essential part of daily life as it is used in footwear,
mattresses, sports goods and raincoats among other things.
Rubber comes from the plantations as field latex and field coagulum. This raw rubber is the processed into Centrifuged Latex(Cenex)PLC crepe rubber EBC crepes and ISNR grades.
