About Polymers and Plastic Materials

Polymers and plastic materials are organic, synthetic or processed polymers that are supplied as raw materials or stock shapes. They typically consist of thermoplastic or thermosetting resins and can be made into many forms. Stock shape forms include sheets, plates, rods, tubes, films, or extruded profiles. Often, thermoplastic resins are supplied as pellets for feeding into molding machines or extrusion presses. Thermosets may be supplied as two-part liquid resins such as epoxies, or as a non-flowing mass premixed with fiber reinforcement. Polyester bulk molding compounds (BMC) are an example of this latter form. Water-based resins, water-born resins and latex products are plastics and plastic materials that consist of resin or polymer droplets that are dispersed and suspended in a water carrier or solvent.

Products & Services Related to Polymers and Plastic Materials

Conductive Adhesives and Compounds

Conductive adhesives and compounds provide an electrically and/or thermally conductive path between components.

Conformal Coatings

Conformal coatings encapsulate circuit boards and their electronic components in order to prevent the ingress of moisture, fungus, dust and other environmental contaminants.

Epoxy Adhesives

Epoxy adhesives are chemical compounds for joining components. They require clean surfaces and are valued for their toughness and resistance to chemical and environmental damage.

Gel Elastomers

Gel elastomers are highly viscoelastic polymer gel materials that have excellent shock absorption and damping characteristics. They are available in a variety of material types and grades.

Pressure Sensitive Adhesives (PSA) and Contact Adhesives

Pressure sensitive adhesives (PSA) and contact adhesives adhere to most surfaces with very slight pressure. They are available in solvent and latex or water-based forms.

Silicone Adhesives and Sealants

Silicone adhesives and sealants have a high degree of flexibility and a very high temperature resistance (up to 600° F), but lack the strength of other epoxy or acrylic resins.

Thermoplastics and Thermoplastic Materials

Thermoplastics and thermoplastic materials soften when heated and harden when cooled. They can withstand many heating and cooling cycles and are often suitable for recycling.
