Self Adhesive & Reinforced

Scene 2 (6s)

SELF ADHESIVE MONOMERIC POLYMERIC

Monomeric - 1- 2 Years Monomeric - 2-3 Years Polymeric - 3-5 Years Polymeric - 5-7 Years Polymeric - 5-10 Years WHAT DO WE MEAN BY MONOMERIC OR POLYMERIC VINYLS??? DEF: Molecular weight of the Plasticiser

Scene 3 (21s)

What is a Plasticiser?

Plasticiser is a chemical that is added to PVC to make it flexible. Monomeric Plasticiser has a low molecular weight Polymeric plasticiser has a higher molecular weight WHY IS THIS IMPORTANT ? The quality of the plasticiser is responsible for the performance of the vinyl Monomeric(low MW means short term application) Polymeric (high MW means long term application) NOTE: Plasticiser is cosmetic-will want to leave the vinyl-plasticiser migration

Scene 4 (44s)

CAST AND CALENDERED VINYLS

Definition-Cast : manufacturing process whereby all additives are blended and the correct viscosity is reached using solvents. The mixture is then applied to a film with a relevant thickness gauge and allowed to cure. (thinner vinyls are cast) Definition- Calendered : manufacturing process whereby the additives are blended and pressed between rollers and stretched to the relevant width. The thickness is governed by the distance between the rollers.(thicker vinyls are calendered )

Scene 5 (1m 8s)

CAST VS CALENDERED

Polymeric Plasticiser Improved UV stability Thermoformable Conformable to curved surfaces

Calendered

Monomeric or polymeric plasticer Limited UV stability-higher UV degradation Higher shrinkage More susceptible to stress cracks and tear

CAST

SELF ADHESIVE VINYL APPLICATIONS

SIGNAGE-Illuminated and non illuminated SIGNAGE-thermoformable SIGNAGE-Digital Printing ARCHITECTURAL-Decorative POS

Scene 7 (1m 32s)

Reinforced PVC

Definition: Polyester scrim coated with PVC commonly known as Flexface /banner material/ flexible substrates Note: 1. The strength depends on the scrim( threadcount ) 2. The weight depends on the coating of the PVC
