The features of Kankyo-woodⅡ

The features

In comparison with Natural-wood

Manufacturing process

 Kankyo-wood II uses waste wood material and a thermoplastic resin, “olefin recycled plastic” Waste wood materials, used as base raw material, are collected from demolished building materials, thinned materials and

industrial waste materials, pulverized into the size of couple of 100 μ

Mixing and kneading pulverized recycled plastics with the base material, Kankyo-wood II is molded through extruder

Resource Recycling Circulation

Waste Wood 40-55％

Others 15％

Waste Plastics 30-45％

Sliding performance test result by JIS A 1454

Note）

Test result measured by slip testing machine is called skid resistance coefficient C.S.R

It is considered as an index that indicates a proper human slipping level while walking

*C.S.R range varies from 0.00～0.99, smaller it slips more and bigger it slips less）

*In architecture field, C.S.R less than 0.4 is considered as “dangerous slippery level”

Consideration）

All material became the surface temperature more than

temperature, but Kankyo-woodII was the value that was approximately

similar to Natural Wood(Ipe).
