Sponge & Foam Rubber Components Features & Capabilities

  • Material Options: Silicone, EPDM, Neoprene, Polyurethane, Nitrile, and specialty blends
  • Performance: Open-cell for cushioning, damping, and sound absorption; closed-cell for weather-, fluid-, and pressure-resistant seals
  • Configurations: Molded to shape or fabricated from sponge sheets (die-cut, waterjet, or laminated)
  • Reinforcement: Options for fabric-reinforced silicone, laminated covers, or bonded assemblies
  • Compliance: FDA, NSF/ANSI, UL (flame-rated), RoHS, REACH, and MIL-STD specs available
  • Finishing: Adhesive-backed options for peel-and-stick installation; precision trimming for flash-free sealing

Why Choose R&R Rubber

Why R&R Rubber Is the Trusted Choice for Sponge & Foam Rubber Components

Sponge rubber isn’t just soft – it’s technically demanding. At R&R, we bring specialized knowledge and hands-on experience to ensure consistent cell structure, proper density, and clean surfaces without defects like excessive skin.

We understand the behavior of sponge materials during molding, extrusion, and fabrication, which means your parts perform reliably and look professional.

Not sure which sponge or foam to use?

We guide you to the right choice:

  • Closed-cell EPDM for outdoor weather seals (UV/ozone resistant, SAE J18 compliant)

  • FDA-grade silicone sponge for food-safe gaskets

  • Flame-rated foams meeting UL requirements for transit and electronics

  • Specialty blends like polyurethane for cushioning or vibration damping

Every material is backed by compliance with FDA, NSF/ANSI, UL, RoHS, REACH, and MIL-STD specs — so your parts are audit-ready and application-approved.

We go beyond supplying sheet sponge — we fabricate to fit.

Options include:

  • Adhesive-backed strips for easy installation

  • Custom shapes molded for cushioning, sealing, or insulation

Our in-house capabilities mean faster turnarounds, better fit, and reliable seals that withstand repeated compression cycles in aerospace, defense, oil & gas, food, and construction applications.
