工艺简介(Basic
Process)：
珍珠棉是非交联聚乙烯泡沫材料，由低密度聚乙烯经物理发泡产生无数的独立汽泡构成。为半硬质地，柔软、弹性好，具有优良的隔热、防震性能，亦具有很好的抗化学和防水性能。
EPE
non-cross-linked polyethylene foam, constituted by the low density polyethylene
by physical foaming numerous independent bubble. Semi-hard texture, soft,
flexible, excellent insulation, shock resistance, and also has good resistance
to chemical and water resistance.
