Synthomer offers a broad portfolio of polyvinyl acetate and poly vinyl alcohols, homopolymers and co-polymers, to meet a variety of needs in diverse markets.
Our polyvinyl acetate homopolymers and acid copolymers are thermoplastic solids supplied in a variety of molecular weights, typically in the form of small beads. These polymers achieve improved performance in many applications including:
- Polyester composites – providing superior shrink control and low profile effects in SMC, BMC and pultrusion moldings
- High performing solvent based adhesives – including hobby, parquet and laminating adhesives
Additionally, Synthomer also supply specialised, ready to use polyvinyl acetate solutions. These are often used in the formulation of penetrating primers and for paper or fabric saturation.
- Thermoplastic and adhesive.
- Very low odour.
- Good compatibility with plasticisers.
- Wide range of solvent solubilities.
- Convenient, time-saving ready to use PVOH solutions available.

ALCOTEX WD100 |
PVOH |
Alcotex WD100 is an aqueous solution of a 43% hydrolysed polyvinyl alcohol. It has been specifically developed by Synthomer Ltd as a secondary suspending agent for vinyl chloride polymerisation. Infinitely dilutable in water, and with an extremely low methanol content, Alcotex WD100 offers increased PVC resin porosity and reduced levels of gels or ‘fish eyes’ when compared to traditional products.In optimised recipes, improvements can be obtained in the porosity/bulk density relationship. Better porosity facilitates both monomer removal and plasticiser uptake. These criteria are further enhanced when Alcotex WD100 is used with the Alcotex range of primary suspending agents.
Alcotex WD100 is also compatible with other conventional primary suspending agents.
NMR measurements have shown that Alcotex WD100 has a random distribution of acetate groups.
The data below represents typical values obtained with different batches of Alcotex WD100. |
