Product Overview
EPDM automotive sealing strips yog tsim los muab lub sijhawm ntev - tiv thaiv dej, plua plav, huab cua to, cua nrov, thiab kev co hauv cov neeg caij tsheb, tsheb thauj mus los, tsheb npav, thiab tsheb fais fab. Piv nrog rau cov khoom siv roj hmab, EPDM tswj tau zoo heev elasticity tom qab ntev raug rau UV hluav taws xob, ozone, noo noo, thiab kub hloov pauv, ua rau nws yog ib qho ntawm cov khoom siv dav tshaj plaws rau sab nrauv tsheb sib khi.
Ntawm BRT Roj Hmab, peb tsim kev cai EPDM sealing strips los ntawm kev nruam extrusion thiab vulcanization txheej txheem kom ua tiav qhov profile ruaj khov, zoo ib yam hardness, thiab txhim khu kev sealing kev ua tau zoo. Txawm hais tias koj xav tau cov khoom siv, daim txhuam cev, lossis co-extruded profiles, txhua lub foob raug tsim los ua kom haum rau koj cov kev xav tau ntawm kev teeb tsa, compression quab yuam, thiab ib puag ncig kev pabcuam.

Tshwj xeeb Profile Structures & Extrusion Options
Co-Extruded Dual-Durometer Seals nrog Steel Carrier
• Kev tsim kho: Rigid EPDM puag embedded nrog segmented steel los yog hlau mesh cab kuj, ua ke nrog ib tug mos daim txhuam cev EPDM sealing noob.
• Lub luag haujlwm tseem ceeb: Cov hlau txuas txuas txuas nrog cov ntawv hlau flange ruaj ntseg yam tsis muaj kua nplaum, thaum lub teeb ntawm tes muab cov mos mos rau lub qhov rooj thiab lub cev.
Iav Khiav Channels & Weatherstrips nrog Flocking / Txheej
• Kev tsim kho: Khoom lossis co-extruded U-channel nrog electrostatic flocking los yog qis- txhuam polyurethane (PU) plam-coat siv rau daim di ncauj sealing.
• Lub luag haujlwm tseem ceeb: Txo cov zawv zawg kev sib txhuam tiv thaiv cov iav qhov rais, tshem tawm cov suab nrov nrov, thiab tiv thaiv kev puas tsuaj.
EV Battery Enclosure Seals (IP67 / IP68 Rated)
• Kev tsim kho: nplaim taws-retardant (UL94 V-}0 / FMVSS 302) kaw- xov tooj ntawm tes daim txhuam cev EPDM nrog ua ntej- siv cov nplaum nplaum (PSA) daim kab xev.
• Lub luag haujlwm tseem ceeb: Tiv thaiv kom tsis txhob ya raws, plua plav nkag, thiab thermal runaway propagation nyob rau hauv hluav taws xob tsheb roj teeb pob.
Kev cai Moulded Corner & Nplhaib Seals
• Kev tsim kho: Extruded profile seem tau koom ua ke txuas mus ntxiv los ntawm kev txhaj tshuaj molding los yog vulcanized splicing.
• Lub luag haujlwm tseem ceeb: xa tawm 100% xau- cov ntaub ntawv pov thawj ib puag ncig rau lub qhov rooj ntawm lub tsheb, lub hnub ci, thiab lub kaus mom tsheb lag luam.
