Elastomer Molded Shape

 

Find Suppliers by Category

Elastomers and rubber shapes are natural or synthetic  polymers that exhibit elastic properties and can be formed into finished or semi-finished stock.  These amorphous polymers are usually thermosets, but are also available as thermoplastics. Elastic polymer (elastomer) and  rubber shapes are available in different forms and sizes, and often use filler materials.

  • Laminated Plastics
    . The molded-laminated method is used to produce shapes that would be uneconomical to machine from flat laminates, where production quantities are sufficient to warrant mold costs. Strength of a molded shape is higher than that of a machined shape because the reinforcing plies are not cut
  • Sealing Challenges For The Medical Industry
    are made of metal and conductive elastomers. Polymers extruded and formed into long pieces with hollow cross sections can be economically formed into a variety of seals, including O-rings and molded shapes. Designing elastomeric seals for pressurized-fluid systems in military and aerospace vehicles
  • MICRO:Top 30 (November/December 2001)
    . Ultra-series materials include compounds offering distinctive physical properties and different performance capabilities. Resistant to steam, water, and a wide variety of chemicals, the materials can be formed into O-rings, molded shapes, slit-valve door seals, and other configurations. They retain
  • Seven Versatile Sealing Materials
    , including physical and mechanical characteristics, shape and cross section, as well as processing methods and how the seal attaches to mating parts. But, undoubtedly, a critical factor is the choice of material. Engineers commonly rely on extruded and molded polymers to seal fluids and protect
  • The expanding role of shrink tubing
    Shrinkable material doesn't just come as tubing anymore. It can take the form of molded shapes and even fabric. Single-walled heat-shrinkable tubing comes in a variety of diameters and colors to insulate contacts, isolate wiring, and blend in with the color scheme ofconsumer goods. Heavy-duty
  • Last Resort Gaskets
    Despite advances in CAD and FEA software, it is still difficult getting molded housings and hardware to fit as planned, especially in handheld electronic devices. It's also not uncommon for performance requirements to evolve during the design. A changing market may dictate whether the device
  • Give cylinder-rod contaminants the boot
    and operating temperatures. Common types of bellows include stitched, vulcanized, injection molded, and an "expanded" type. Standard stitched construction provides sufficient protection against most contaminants in moderately severe applications. The bellows have rings of elastomer-coated fabric sewn
  • Advanced adhesives foster hybrid structures
    with previous versions, lowers costs by 10%, and meets structural requirements. Adhesive bonding of hybrid structures lets designers use molded closed-box sections, which maintain structural integrity and permit more cost-effective materials and thinner wall sections. An emerging trend
