TECHNOPOROUS BLOCK is uniformity and high porosity (low apparent specific gravity) featuring continuous
micro-porous polyurethane foam based on our original unique manufacturing technology. From its inherent softness and hand,
TECHNOPOROUS BLOCK is widely utilized for many uses such as Cosmetic puffs, Eye shadow tips and Liquid medicine coating
foam to the skin.
Even in High-Tech industry, taking advantages of scratch-free, large absorption capacity of water/oil,
no self-generation of particles, TECHNOPOROUS BLOCK is also usable in extensive fields, for example, Wipers, Cushion sheets, Spacers,
Ink storage tanks for printers and so on.
The general properties, e.g. apparent specific gravity, elongation, hardness and pore size of TECHNOPOROUS BLOCK are controllable as per requirements in each use, and TECHNOPOROUS BLOCK is sliced and/or press-cut into any shape and size to order.
