FIELD: process engineering.
SUBSTANCE: set of inventions relates to bar for decorative welding and to method of its fabrication. This bar comprises unfused and painted PVC-based particles and plastisol-based gel composition containing PVC resin in benzoate plasticizer and unfused PVC-based particles. The latter feature size and colour identical or similar to particles used in connected elements of decorative surface. Proposed method comprises the steps that follow: liquid mix of PVC resin in benzoate plasticizer is mixed with PVC-based particles, obtained mix is placed on conveyor belt, heated to gel and sheet formation. plastisol-based gel composition containing PVC resin in benzoate plasticiser. Then, the sheet is pressed to make several welding bars.
EFFECT: higher flexibility, adhesion and melt temperature, ease of cutting.
