A-Resins | Rotomoulding Polymers, a new brand in the rotomoulding industry

    About

    A-Resins | Rotomoulding Polymers is a new brand in the rotomoulding industry, supplying polymers for engineering applications. The first product, ROTARES 1220, is a newly developed, high performance thermoplastic polyester for demanding applications.

    For its development, A-Resins | Rotomoulding Polymers has collaborated with the Polymer Processing Research Centre of Queen’s University in Belfast.

    ROTARES 1220 in Fuel Tank applications

    Due to its high chemical resistance for oils, diesel and (bio)fuels combined with a very low evaporative emission similar to polyamide, ROTARESINS 1220 polyester is very suitable for the production of fuel tanks

    ROTARES 1220 in decorative applications

    ROTARES 1220 is paintable, delivering a smooth surface without pinholes. Due to its high stiffness and good impact, durable decorative applications can be made with this polyester.

    ROTARES 1220 : main characteristics

    ROTARES 1220 is a high performance thermoplastic polyester for rotational moulding.

    It is a newly developed material and Patent Pending.

    ROTARES 1220 is designed for specialty and engineering applications with

    For some rotomoulding applications, this thermoplastic polyester can replace current polyamide resins.

    Other uses are applications where the commodity materials (PE, PP) are technical unsuitable, and when polyamide (-11 and -12) resins are too expensive.

    • high temperature resistance
    • high stiffness with good impact properties
    • excellent chemical resistance for fuels, greases, oils, biofuels
    • very low evaporative emission for hydrocarbons
    • very low dielectric constant (electrical insulator)
    • nice surface characteristics with good scratch resistance and absence of pinholes
    • paintable
    • not suitable for acids and bases

    Applications

    Structural parts

    containers for hydrocarbons

    design applications

    furniture

    electric appliances

    battery hoses

    etc.

    Processing conditions

    ROTARES 1220 polyester can be processed on any convential rotational moulding machine, nitrogen blanketing is not required.

    ROTARES 1220 can also be processed in electrical heated moulds.

    A PIAT between minimum 245°C and maximum 255°C must be respected (Peak Internal Air Temp.).

    It is recommended to keep the product dry prior use for production.
