Common Resins for Flame Retardant Applications

RTP Company develops flame retardant compounds in 60+ engineering resins. These are some of the more popular polymers used for flame retardant applications along with their key features and typical end-uses:

Polypropylene (PP)
RTP 100 FR Series — Excellent fatigue endurance and outstanding chemical resistance. Performs well at operating temperatures up to 225 °F (105 °C).
Applications include: wire and cable jacketing, small appliances, lawn and garden tools, outdoor grating, support brackets, furniture components, toys, and kitchen tools.

Nylon or Polyamide (PA)
RTP 200 FR Series — Superb mechanical properties up to 275 °F (135 °C) in continuous use. Molds easily in thin wall sections; good resistance to chemicals.
Applications include: electrical & electronic connectors, electrostatic painting applications.

Polycarbonate (PC)
RTP 300 FR Series — Superior impact strength, high heat resistance, good electrical properties, excellent mechanical properties up to 250 °F (120 °C). Controlled shrinkage, dimensional stability, thermal stability, good flow, and good surface finish.
Applications include: consumer goods, business machines, housings, and medical devices.

Acrylonitrile Butadiene Styrene (ABS)
RTP 600 FR Series — Continuous use temperatures up to 175 ˚F (80 °C). Easy processing, chemical resistance, increased surface hardness, good impact strength, and overall toughness. Good for plating.
Applications include: housings for business equipment and medical devices.

Polybutylene Terephthalate (PBT)
RTP 1000 FR Series — Good dimensional stability, high heat resistance, chemical resistance. Good flow in thin-wall sections, rapid crystallization, low mold temperatures, and fast cycle times make this material economical to mold.
Applications include: electrical & electronic connectors (preferred over nylon when moisture absorption is an issue).

Polycarbonate/Acrylonitrile Butadiene Styrene Alloy (PC/ABS)
RTP 2500 FR Series — Higher heat deflection temperature than ABS with better low-temperature impact resistance than PC. Good dimensional stability, easily colored.
Applications include: computer and business machine housings, appliances.

Polycarbonate/Acrylic Alloy (PC/PMMA)
RTP 1800A FR Series — Higher impact resistance than PC/ABS with the processing ease of acrylic. Excellent flow, ideal for thin wall molding.
Applications include: portable device housings, lighting fixtures, appliance components, toys, furniture, automotive components, and medical diagnostic equipment.

Thermoplastic Vulcanizate Elastomers (TPV)
RTP 2800 FR Series — Offers a broad range of elastomeric properties in addition to superior heat resistance. Can incorporate with both RoHS compliant and halogen-free FR systems.
