TECHNOPOROUS ROLLER

TECHNOPOROUS ROLLER is a continuous, micro-porous foam roller based on our original technology, excellent in various properties such as softness, resilience, water absorption and chemical resistance. In addition, TECHNOPOROUS ROLLER is made of alternative base polymers of polyolefin or polyurethane, so that the most suitable roller can be selected for diverse uses each. For example, a polyolefin roller is recommendable in a chemical resistance demanding use, and so is a polyurethane roller in an abrasion resistance demanding use.

Note

Test method of chemical resistance

1. Sample size

60mm(L)×10mm(W)×2.5mm(T)

2. Immersion conditions

	In PP container, the sample was submerged under the chemical solution volumetrically 20 times or more the sample for each period.
	Temperature: 25±2
	After the submersion, the sample was washed with a large quantity of running water to eliminate remaining chemicals and dried.

3.Tensile strength measurement

	The two indication lines were put 20mm apart from each other on the lengthward center of the sample, and the measurement was conducted by Tensile Strength Meter of Minebea Co., Ltd.
	Tensile speed: 300mm/min.
