Typical Plastisol Properties
| Property | Value | Test method |
|---|---|---|

| Severs | > 300 g/100 sec | GB/T 21989-2008 |
Test conditions: Plastisol prepared from 100 phr resin and 60 phr DINP, mixed in a Hobart N-50 for 5 minutes at speed 1 and 15 minutes at speed 2. Brookfield viscosity measured after 2 hours aging at 25°C, spindle No. 6 at 50 rpm. Severs measured on 2-hour plastisol at 90 psi.
Applications
Wall covering. Foamed vinyl wallpaper depends on an embossable foam layer with cells fine enough to take a mechanical or chemical emboss without tearing. PR-450 produces the closed-cell structure that holds a pattern, and the medium plastisol viscosity lets coaters control add-on weight on paper and non-woven substrates without starving or flooding the knife.
Floor covering. Cushioned vinyl flooring is built as a foam core between a printed layer and a wear layer, and the foam carries indentation recovery and footfall sound reduction. Uniform cell size is what keeps indentation recovery consistent across a roll. The low DP of PR-450 fuses the foam core at line temperature while the ADCA gas front is still active, so density stays even from edge to edge.
Foam sheet. Free-standing foam sheet and gasket stock need predictable expansion ratios batch to batch. Degree of polymerization held to 1,000 ± 100 keeps the gelation curve consistent, which keeps thickness and density within tolerance on long runs.
Casting leather. Synthetic leather made by release-paper casting requires a plastisol that releases air cleanly and reproduces fine grain detail. PR-450's air-release property keeps pinholes out of the skin coat, and a foamed intermediate layer built on the same resin gives the hand and compressibility buyers expect from upholstery and footwear materials.
Automotive accessories. Interior trim, instrument panel skins, and sound-deadening parts call for tight dimensional control and low volatiles. Volatiles at ≤ 0.40 % limit fogging contribution from the resin itself, and plastisol stability supports the long mixing-to-molding intervals typical of automotive part production.
Why Choose BASTONE
BASTONE carefully sources Formolon PR-450 through an established supply chain network in the Chinese chemical market. BASTONE is the supplier and exporter of the grade, not its manufacturer — the resin ships in original Formolon packaging with the producer's own documentation, so your incoming inspection records trace back to Formosa Industries (Ningbo).
Quality control draws on the group's own chemical expertise. BASTONE operates four production sites and one R&D center across its chemical divisions, and the technical staff who run those operations vet the sourced grades the plastics division trades. Chemists who formulate plasticizers know what a paste resin lot should look like and which incoming test results deserve a second look.
One-stop procurement is the practical advantage for plastisol producers. BASTONE's plastics division supplies plasticizers — DINP, DOTP, DOP, DOA, TOTM — alongside PVC resin and additives, so a foaming formulation can be sourced on a single purchase order with one set of documents and one shipping coordination point. Trade terms stay flexible, and the commercial team handles booking, documentation, and schedule follow-up through to arrival.
