埃克森美孚TPV 211-55

埃克森美孚tpv211-55--以下便是tpv材料的特性以及应用领域的相关介绍，希望能帮到各位很好地明白tpv是何种材料。目前tpv材料多运用于较为高端的制品中，材料成本相对较高，请各位老板依据自身产品定位进行合理采购。

tpv的物理性能及影响因素：

tpv的力学性能是重要的特性之一。其物理性能通常用拉申曲线图来表明。与传统式橡塑制品共混物对比，tpv原材料根据动态性硫化橡胶，塑胶相对高度化学交联及粉碎，造成反过来转，产生以塑胶为分散介质，塑胶为持续相的“海-岛”构造，并促使橡塑制品共混物具备较高的物理性能和延展性特性。多见的pp/epdm-tpv原材料，因为塑胶产生化学交联产生网络架构促使共混物具备更强的塑胶延展性特性，包含弹性模具大、（拉申或缩小形变）。

tpv物理性能关键在于塑胶相的化学交联水平、塑胶/塑料（r/p）构成比、pvc颗粒的规格和尺寸遍布、交联网络构造、塑胶栽培基质的薄厚、塑胶各相塑胶相的相溶性、tpv中的食品添加剂和动态性硫化橡胶（dv）标准等。

mechanical properties and influencing factors of tpv:

the mechanical properties of tpv are one of the most importantproperties. its mechanical properties are usually expressed bytensile curve. compared with traditional rubber and plastic blends,tpv materials are highly crosslinked and broken through dynamicvulcanization, resulting in phase inversion, forming a "sea island"structure with rubber as dispersed phase and plastic as continuousphase, and finally making the rubber and plastic blends have highermechanical properties and elastic properties. the most common pp /epdm-tpv material has better rubber elastic properties, includinglarge elastic modulus and small permanent deformation (tensile orcompressive deformation) due to the crosslinking of rubber and theformation of network structure.

the mechanical properties of tpv mainly depend on thecrosslinking degree of rubber phase, rubber / plastic (r / p)composition ratio, size and size distribution of rubber particles,crosslinking network structure, thickness of plastic matrix,compatibility between plastic phase and rubber phase, additives intpv and dynamic vulcanization (dv) conditions.
