    Acrylic Processing Aids(PVC 發泡調節劑)

    1 Introduction

    The addition of PVC processing aids LS-530 to rigid PVC formulations is a processing aid based on a high molecular weight polymethacrylate resin. LS-530 improves the processability and the performances of PVC formulations.

    2 Performance

    Promote gelation of PVC, Improve hot-melt strength and visco-elasticity, Stabilize the microcells generated by blowing agents to achieve the low density and high strength of the foam. Increase the surface quality of PVC products.

    Better dispersion of additives into PVC, more homogenous melt of PVC, etc. LS-530 has been used in weatherable applications and is widely used in PVC building products.

    3 Application

    LS-530 are mainly used in PVC profiles, foam pipe, foam profiles, foam sheet, wood composites,etc.

    Addition levels for this application are 5-8 phr(PVC 100 phr).

    4 Physicochemical Properties

    LS-530 is White fluid powder, banked specific gravity:0.45-0.55g/cm3, can not be dissolved in water, ethanol, can be dissolved in chloroform and methyl ethyl ketone.

    5 Quality Criteria

    Index/Product NameLS-530

    AppearanceWhite fluid powder

    Granularity(throughput efficiency of 40 mesh)(%) 98

    Volatile component(%) 1.0

    Limiting viscosity number( )(Ubbelohde Viscometer)4.5-6.5

    6 Storage, Packing & Transportation

    Packaged in airproof plastic bag, then in woven bags with quality certificate, the outside of bags is marked with brand, company name, net weight of products, lot identification mark .Avoid insolation , drench.

    Stored in cool and draughty place, shelf life: one year.
