SEJ BOARDS
SHALITEX EXPANSION JOINT BOARD is manufactured from water resistant, bitumen impregnated, cane fibre  Softboards. It is available in a wide range of sizes, both as boards & strips in thicknesses of 12mm, 18mm & 25mm.

SHALITEX EXPANSION JOINT BOARD displays excellent resistnace to compression, with outstanding recovery characteristics. The boards are environment friendly as opposed to the environment destroying thermocole/plastic expansion joint boards.

Softboard is usually made from bagasse. Bagasse is converted to pulp either by wet grinding on abrasive stone, rotating at high speed. Unwanted impurities are removed and several refining and screening stages are included in the manufacturing process to make the pulp thin and fine.

The thin pulp produced by the above process is mixed with a small percentage of sizing additives and is fed on to a forming machine consisting mainly of a long conveyor belt.  Here most of the water is drained, sucked and pressed out of the pulp.  A continuous strip  of wet board so made is rolled to thickness cut into lengths and passed through the drying chambers.  The dried board thus coming out is the final softboard which is trimmed and cut into standard sizes.
