汽车仪表板PVC和TPU搪塑表皮性能研究

The Property Study of Auto Instrument Panel PVC and TPU Slush Skin

摘要: 大多数汽车仪表板搪塑表皮采用PVC，仅有少量车型使用TPU，故对PVC和TPU搪塑表皮性能对比研究的报道较少。本文对比研究了PVC搪塑表皮和TPU搪塑表皮的性能，结果表明PVC搪塑表皮的拉伸强度优于TPU搪塑表皮的拉伸强度，二者韧性相当；PVC搪塑表皮的散发性能优于TPU搪塑表皮；二者耐磨和耐化学试剂的测试结果相当；TPU搪塑表皮老化性能略优于PVC搪塑表皮。

Abstract: PVC was used by most auto instrument panel slush skin, only a few used TPU. So the report which studied the properties of PVC and TPU slush skin is less. In this Paper, PVC and TPU slush skin property were comparatively studied. The results show that the tensile strength of PVC slush skin is better than that of TPU, the toughness is similar. PVC slush skin emission test result is better than TPU; the test results of abrasion resistance and chemical reagent resistance are similar; aging performance of TPU slush skin is a little better than that of PVC.
