China donfoam 901 mvura base benld polyls yekudurura mugadziri uye mutengesi

Donfoam 901 mvura inokonzeresa benld polyols yekudurura

Donfoam 901 mvura yeBase Benld Polys yekudurura Inotsanangurwa mufananidzo

Tsananguro pfupi:

Ichi chigadzirwa rudzi rwepamhepo rwakasanganiswa ne 100% mvura sekuputika mumiririri, iyo inoshambidzwa zvakanyanya kuomarara yechienda.

Hunhu hwakateedzerwa:

● Kuyerera kwakanaka, kwakakodzera kudururwa kwenguva imwe chete.

● Zvakanakisa Foam Mechanics Properties

● Yakanyanya kukwirira / yakadzika tembiricha yekudzikama kugadzikana

Introdution

Ichi chigadzirwa rudzi rwepamhepo rwakasanganiswa ne 100% mvura sekuputika mumiririri, iyo inoshambidzwa zvakanyanya kuomarara yechienda. Hunhu hwakateedzerwa:

(1) Kuyerera kwakanaka, kwakakodzera kudururwa kwenguva imwe chete.

(2) yakanaka kwazvo foam mechanices zvivakwa

(3) Yakanakisa yakakwirira / yakadzika tembiricha yakadzika kugadzikana
