Detail Description

Iyo polyurethane elastomer yakasungirirwa pamusoro pedhiramu chinhu chitsva chepolymer synthetic pakati perabha nepurasitiki, ine zvese zvesimba rakakwirira uye elasticity yepurasitiki nerabha.

Iine maitiro anotevera:

1.Wide kuomarara range. Ichiri nekurebesa uye kusimba kwerabha pasi pekuoma kwakanyanya. Hukukutu hwemhando ye polyurethane elastomer ndeye Shore A10-D80.
2.High simba. simba ravo rekuputsa uye simba rekutakura rakakwirira zvikuru kupfuura rerabha yepasi rose pasi pekuoma kwakafanana. Pakuoma kwepamusoro, simba rayo rekuita uye simba rekukotama rakakwira zvakanyanya kupfuura epurasitiki.
3.Kushongedzwa kwekupfeka kunonyanya kukosha, kazhinji muhuwandu hwe 0.01-0.10 (cm3) /1.61km, inenge 3-5 nguva yerubha.
4.Excellent mafuta kuramba. Polyurethane elastomer imhando yakasimba yepolar polymer compound, ine hukama hushoma neasiri-polar mineral oiri, uye inenge isina kukoromoka mumafuta ehuturu nemafuta emuchina.
5. Good oxidation uye ozone kuramba.
6. Yakanakisa vibration absorption performance, ine vibration kuderedza, buffer effect.
7. Good low temperature performance.
