À propos RNTIC Rubber Sealing Strip

RNTIC is a professional custom extruded rubber sealing strip manufacturer from China. We produce EPDM, Nbr, silicone, neoprene sponge & solid rubber stripping to solve waterproof, dustproof, résistant à l'huile, and high-temperature sealing problems for automotive, construction, and industrial equipment.

All rubber seal strips support custom cross-section, taille, couleur, and hardness per your 2D/3D drawings or samples.

Below are all types of extruded rubber sealing strips RNTICO can customize and produce:

Solid rubber sealing strips
Joints en caoutchouc éponge
Extrusions de joint en caoutchouc à double duromètre
Profilés en caoutchouc coextrudés avec support métallique

Notre gamme de produits de bandes d'étanchéité en caoutchouc extrudé

We provide multiple rubber material options for custom sealing strips, covering weather resistance, résistance à l'huile, résistance aux hautes températures, flame retardant and other performance requirements, suitable for different complex working scenarios.

EPDM Weather-Resistant Rubber Seal Strip

EPDM ranks as our most popular outdoor sealing material. It features excellent UV, rainwater, et résistance au vieillissement, along with good elasticity and compression resistance.

Pour cette raison, we use EPDM seal strips for truck door weatherstripping, construction window gap filling, and ship hatch waterproof sealing. It can effectively prevent water leakage, dust ingress, and aging failure caused by long-term sun and rain exposure.

Oil-Resistant NBR Nitrile Rubber Sealing Strip

NBR material delivers top-tier resistance against oil, porter, and tearing. Specifically, it works perfectly in spaces that touch mineral oil, diesel, gasoline, and lubricant oil.

We supply NBR seals for excavator cabin enclosures, hydraulic tank surrounding gaskets and kitchen mechanical oil contact parts. These strips maintain steady sealing performance and extend service life for industrial leak prevention.

High temp resistant solid silicone rubber sealing strip for oven & auto engine

High & Low Temp Resistant Silicone Rubber Seal Strip

Silicone rubber sealing strips offer excellent resistance to extreme temperatures, remaining stable from –60°C up to 250°C. They are eco-friendly, soft to the touch, and fully weatherproof.

These strips perform reliably across a wide range of applications, including household appliances, automotive engine compartments, and high-temperature industrial sealing systems.

Flame Retardant Neoprene Sponge Rubber Seal Strip

Néoprène (CR) sponge sealing strips feature reliable flame retardancy. Besides, they absorb vibration, muffle noise, and stand up to chemical corrosion.

Thanks to their porous sponge structure, these strips offer great compression rebound and air tightness.

For industrial use cases, we fit these seals into fireproof equipment, electrical cabinets, and all shock & sound insulation assemblies. They efficiently isolate vibration, cut down noise, and shield parts from outside corrosive fumes.

Other Optional Raw Materials for Custom Sealing Strips

In addition to the above conventional materials, we also provide natural rubber, FKM, PVC, and other special material sealing strips, which can be customized according to your special working condition requirements, such as wear resistance, résistance à la corrosion, and ultra-low temperature resistance.

Co-Extruded Rubber Sealing Strip Solutions

We build professional co-extrusion composite rubber profiles to meet strict sealing and structural stability standards. Our custom service covers two core composite types: dual durometer sponge-solid rubber extrusions and metal-reinforced rubber strips. Both fix common flaws of single rubber strips, such as weak support and loose-fitting gaps.

Dual Durometer Sponge and Solid Rubber Extrusions

Dual durometer co-extruded rubber seal integrates solid rubber and sponge rubber into one piece through one-time co-extrusion molding.

The solid part provides strong support and fixing performance. D'autre part, the sponge part adds elasticity and tight sealing. It has excellent compression resilience and air tightness. We widely apply this design for car doors, fenêtres, container hatches, and other airtight sealing scenes.

Extruded Rubber Profiles With Metal Insert

Metal insert co-extruded rubber sealing strip is compounded with galvanized steel sheet or aluminum sheet inside the rubber body. The metal framework enhances the overall structural stability and shape retention of the sealing strip, avoiding deformation and falling off after long-term use.

Ces bandes d'étanchéité en caoutchouc composite renforcé d'acier combinent les avantages du métal et du caoutchouc., garantissant des performances d'étanchéité et une durée de vie supérieures.

Les profils de joints en caoutchouc de coextrusion sont largement appliqués dans plusieurs industries, y compris le transport, automobile (comme bandes d'étanchéité en caoutchouc pour automobiles), industrial equipment, et portes de chantier & fenêtres.

De quels matériaux sont faites les bandes d'étanchéité en caoutchouc extrudé RNTICO?

Nous proposons de l'EPDM, Nitriles, Silicone, Néoprène, NR, FKM, PVC, TPE, T.V.A., etc., pour répondre à différentes conditions de travail.

Pourquoi les bandes d'étanchéité en caoutchouc sont-elles importantes?

En tant que composant clé d’étanchéité, les bandes d'étanchéité en caoutchouc prolongent non seulement la durée de vie des équipements et des structures, mais améliorent également considérablement les performances du produit, sécurité, et expérience utilisateur.

RNTICO peut-il personnaliser la bande d'étanchéité en caoutchouc?

Oui, nous soutenons solide, mousse, creux, special-shaped cross-sections and tailor-made sizes based on your 2D/3D drawings or samples.

Quelle est la période de production de la bande d'étanchéité en caoutchouc personnalisée dans RNTICO?

Lead time varies by size, cross-section complexity, and quantity. Reach out for specific details.

Comment sélectionner le bon matériau pour les bandes d'étanchéité en caoutchouc?

Choose materials based on your working conditions (weather/oil/temp resistance), material traits (EPDM, Nbr, silicone), technical specs, and budget. Our team can help you pick the best fit.

Quelle est la différence entre les bandes d'étanchéité en caoutchouc plein et en mousse?

Solid sealing strips are dense, porter & pressure resistant for tight heavy-duty sealing. Foam sealing strips are soft, élastique, with great sound/heat insulation, fit low-pressure filling scenarios.
