“ rigid degree ” is material 体发生 mono 位形变时 need force large small; “柔 degree ”则指 material in mono force lower 发生 形变 large small. “ rigid degree ”越 large, 越不容 easy deformation; “柔 degree ”越 large, easy deformation. tough property good material comparison soft/flexible, tensile fracture elongation, impact resistant strong/high degree relatively large, hardness, tensile strength and tensile elastic property modulus relatively small.

from above can 看出, rigid degree and tough property for 立态, for modified plastics products 而言, 两者会 versus 互依存. use glass fiber reinforced plastics rear, it rigid property large meanwhile, can can tensile strength and impact strong/high degree increase.

how to improve/increase plastics tough property?

through for plastics products testing 发现, improve/increase resin tough property has improve/increase toughened plastics toughened 效果.

toughened very more, ratio increase large resin molecular weight, make molecular weight distribution narrow small, or control is crystallization and crystallization degree, dimensions and type and other methods high toughness.

how to separation plastics commonly used toughening agent?

橡胶 elastomer toughened

EPR（ binary 乙丙）, EPDM（ ternary 乙丙）, 顺丁橡胶（BR）, 天然橡胶（NR）, 异丁烯橡胶（IBR）, ***橡胶（NBR） and other; suitable for has plastics resin toughened modified;

thermoplastic property elastomer toughened

SBS, SEBS, POE, TPO, TPV and other; more used for polyolefin or non property resin toughened, used for polyester type, polyamide (PA) type and other has property can polymer toughened add compatibilizer;

核- housing/shell copolymer and reaction type terpolymer toughened

ACR（ acrylic ester type ）, MBS（ acrylic ester - butadiene - styrene copolymer ）, PTW（ ethylene - acrylic ester — methacrylic acid sink marks ester copolymer ）, E-MA-GMA（ ethylene - acrylic ester — methacrylic acid sink marks ester copolymer ） and other; more used for engineering plastics and high temperature resistance polymer/macromolecule alloy toughened;

high toughness plastics blending toughened

PP/PA, PP/ABS, PA/ABS, HIPS/PPO, PPS/PA, PC/ABS, PC/PBT and other; polymer/macromolecule alloy technology is made high toughness engineering plastics important 途径;

its it methods toughened

nano pellets toughened （如 nano CaCO3）, *** resin （ DuPont metal ionomer ） toughened and other.
