3、 HNBR .

Hydrogenation degree a san chuan HNBR-a heat resistance a tha zawk a, a chhan chu main chain-ah unsaturated double bond a awm lo tluk a ni a, chu chu unstable a ni. HNBR thenkhat chu sulfur hmangin an la vulcanized thei tho a, a chhan chu unsaturated double bonds engemaw zat an la neih vang a ni. Mahse, peroxide hmanga vulcanized a nih chuan compound-a heat resistance chu a tha zawk ang. HNBR rubber tan chuan TOTM hian DOP aiin heat resistance tha zawk a pe thei a, a chhan chu heng trioctyl plasticizers te hi volatility hniam leh molecular weight sang tak a nih vang a ni.

4. Neoprene .

W-type neoprene hian G-type neoprene aiin heat aging resistance a nei tha zawk. Diphenylamine octanoate hi neoprene tan chuan antioxidant tha zawk a ni a, hei hian a lumna dona a ti tha thei hle.

5、 EPDM .

EPDM hian fit tha tak hnuah pawh 125°C ah heat resistance tha tak a la nei ang. Peroxide vulcanized EPDM hman hian rubber hian heat resistance a nei tha zawk thei.

6、 Low viscosity vapor phase method EPDM .

Ethylene tamna leh ultra-low viscosity vapor phase EPDM, filler tam takin a khat thei a, ethylene tamna a nih avangin, processing-ah chuan heat-resistant air aging unfavorable and resin processing-a tel a ngai lo va, rubber chu processing property tha tak nen a la siam thei tho a, chuvangin rubber lumna tak tak chu a siam tha thei a ni.

7、 High styrene resin hman loh tur a ni.

Temperature sang taka hman rubber-ah hian high styrene resin dah loh tur a ni.

8、 talcum powder a ni.

EPDM hose rubber ah chuan carbon black 40% chu talcum powder hmangin thlak la, hei hian rubber a heat aging resistance a ti tha thei. Talcum powder grade thenkhat chuan he thil chungchangah hian leilung enkawl emaw enkawl loh emaw aiin hlawkna langsar zawk an nei a ni.

9、 Viscosity sang tak plasticizer .

Plasticizer zingah hian viscosity sang tak plasticizers hian low viscosity plasticizers aiin heat aging resistance tha zawk a pe thei a ni. A chhan chu viscosity sang tak plasticizer hian molecular weight sang tak a nei tlangpui a, volatilize awlsam a ni lo va, chu chuan stability tha tak leh heat resistance tha tak a nei a ni.

10、Enoprene tan 10、Rape Seed Oil .

Neoprene hian resilience tha zawk a neih theih nan canola oil hi a mamawh a, a chhan chu viscosity a hniam vang a, chu chuan rubber chu hysteresis a nei tlem a, volatility a nei tlem a, chu chuan rubber chu aging resistance tha tak a nei thei a ni.

11、EV/Semi-Effective SEV Vulcanization system tha tak

Vulcanization system angkai emaw, semi-effective emaw-ah chuan, accelerator leh sulfur ratio chu a sang a, chu chu, 'sulfur leh sulfur low sulfur' system, sulfur pakhat aiah 'sulfur to the body' a ni a, he vulcanization system-ah hian sulfur pakhata bond pakhat leh sulfur bond-a double sulfur bond-a double sulfur a awm zat chu a sang zawk a ni, a chhan leh double sulfur bond chu multi-sulfur bond aiin a sang zawk a, chuvangin, rubber-a heat resistance stability a tha a, heat aging resistance pawh a tha zawk bawk.

12、Zinc Oxide 2019 a ni.

Vulcanization / sub-sulfuramide Vulcanization system, zinc oxide tam zawk nena khat, rubber chu heat aging property tha zawk leh post-sulfur laka invenna tha zawk a pe thei a ni.
