Stockwell Elastomerics, Inc. Entries

  • ►  Gaskets • Rubber Gaskets • Silicone Gaskets 

    For: Entry

    Stockwell Elastomerics Inc manufactures a line of silicone gaskets that includes injection molded gaskets, silicone foam gaskets, sponge silicone gaskets, solid silicone gaskets, and custom gaskets. The sponge gaskets are for NEMA 4 and IP-65 environmental seals, while the solid gaskets are commonly used on metal enclosures. Used within electrical enclosures, the foam gaskets feature a flame rating of UL94-V0. The injection molded gaskets provide improved sealing integrity for water submersion requirements.

  • ►  Gaskets • EMI Gaskets 

    For: Entry

    EMI gaskets are used in applications where electromagnetic interference isolation is required, commonly between the shield housing and mating surface of a device.

    A custom manufacturer, Stockwell Elastomerics Inc. produces EMI gaskets, EMI/RFI gaskets, and EMI shielding gaskets for commercial and military/aerospace applications. The company's military EMI gaskets meet MIL-G-83528C specifications.

  • ►  Gaskets • Foam Gaskets 

    For: Entry

    Foam gaskets are made in open and closed cell types and are used for a wide variety of applications from noise dampening to gas sealing.

    Stockwell Elastomerics Inc. is a provider of silicone foam gaskets that varying in cell structure from very open cell to mostly closed. The open celled models can be used for dust seals or shock/vibration gaskets, while mostly closed celled gaskets are used for environmental seals. All the foam gaskets have a flame rating of UL94-V0 for electrical enclosure use.

  • ►  Gaskets • High Temperature Gaskets 

    For: Entry

    High temperature gaskets are used in extreme heat applications and come in a variety of materials.

    Stockwell Elastomerics manufactures custom high temperature gaskets from various high temperature gasket materials, a few of which are readily available with operating temperatures in the 400 – 500 F (204 – 260 C) range with intermittent temperatures up to 600 F (333 C).

  • ►  Gaskets • Adhesive Backed Gaskets 

    For: Entry

    Adhesive backings are applied to a wide range of gasket materials, including: silicone, sponge, foam, solid rubber, sponge rubber, EPDM, neoprene, PVC, etc.

    Stockwell Elastomerics offers PSA gaskets, pressure sensitive adhesives and adhesive gaskets. Self-adhesive gaskets include acrylic for temperatures from -40F to 350F, low tack and re-positioning adhesive for systems that might require reseating, pressure sensitive silicone adhesive for use with temperatures ranging from -80F to 450F and pressure sensitive adhesives when EMI shielding/ESD grounding is necessary.

  • ►  Rubber • Rubber Compression Molding 

    For: Entry

    Molding method where rubber material is placed in an open heated mold cavity, followed by a top lunger applying force to rubber material forcing it into shape until material is stable.

    Stockwell Elastomerics, Inc. is a rubber component manufacturer for the OEM market. Rubber compression molding services are available for silcone parts as well as specialty materials such as electrically conductive nickel-graphite filled silicone, silver plated aluminum filled silicone and carbon filled conductive silicone as well as fluorosilicone rubber compounds.

  • ►  Rubber • Silicone Molding 

    For: Entry

    Molding made from silicone, an extremely flexible and easily prepared/removed material that is excellent for gum paste modeling applications.

    Stockwell Elastomerics, Inc. offers liquid and custom silicone molding for the following applications: cushioning pads, devices, seals, gaskets, rugged electronics, sensing instruments, portable communications devices, etc. Stockwell also offers cryogenic de-flashing systems for removing parting line flash from hard to reach areas on complex or simply-molded parts. These systems are capable of reducing flash conditions from 0.005" to 0.015" long.

  • ►  Rubber • Silicone Sheet 

    For: Entry

    Sheeting made from silicone, a strong yet flexible material typically used for a wide variety of laboratory and general medical applications.
