PVC 741E


PVC 703E is a fine particle, medium molecular weight PVC homopolymer, made by emulsion polymerization. It is designed for the manufacture of plastisols exhibiting high viscosity and high yield value at low shear rates with pseudoplastic flow characteristic at high shear rates with plasticizer concentration equal or higher than 70 Phr. Because of the high viscosity of PVC 703E pastes, this resin is recommended primarily for highly plasticized applications. Plastisol made from this resin exhibit the following main properties:
Low gelation temperature Long shelf life, low viscosity ageing Little tendency to sediment Good thermal stability
 
Product Description:
PVC 741E is a fine particles, high molecular weight PVC homopolymer, made by emulsion polymerization.
It is designed for the manufacture of plastisols exhibiting low viscosities at low shear rates and slightly dilatant flow characteristic at high shear rates with plastizer concentration of (40 –60) Phr.
Plastisol made from this resin exhibit the following properties:
Long shelf life, low viscosity aging.
Low plastisol viscosity
Easy gelation
No tendency towards settling out.
High abrasion resistance
Good thermal stability with a range of standard stabilizers.
Low percent of oversized particles
High filler tolerance
Good drum gelling
Applications:
Pastes made from PVC 741E are ideal for compact, clear thin coating, and also for chemically blown spread coatings with low plasticizer content. PVC 741E pastes are particularly suitable for: Spread coating of compact layers of low-to medium plasticizer levels having good mechanical properties (conveyer bells, tarpaulins) and good transparency (raincoats, swimming pool liners, tablecloths).
Spread coating of compact, thin layers made at high speed (wall covering, top coats).
Spread coating of chemically blown layers with low plasticizer content (handbags, luggage) or With medium-plasticizer and high-filler content (vinyl-backed carpets, cushioned vinyl floor coverings).
Screen coating of textured foamed wall covering.
PVC 741E is also suitable for other processes, e.g. rotational molding, slush molding and dipping.
