Caplugs considers it extremely important that our employees work with the highest quality materials. The use of clean materials in our production process, which are not hazardous for man or the environment, has our continuous attention (consider here our standard phthalate-free materials for a number of colours).

Vinyl plastisol is a dispersion of polyvinylchloride (PVC) resin in a liquid plasticizer. Other ingredients are pigments, stabilisers for heat and UV light, flame retardants and additives that influence the surface (matt/gloss).

An extensive range of plastisol qualities is available for a wide range of applications and Caplugs has been involved in the development of many special formulations. The hardness is determined by the level of plasticizer and is measured using the Shore A scale from a flexible 40 Shore A to a dimensionally stable 95 Shore A.

Runners and Gates of PET Injection Mold All conventional types of gates can be used. Gates should be 50–100% of the part thickness.

Caplugs offers a complete range of standard colours and can match an exact colour if required. The standard finish for dip moulded products is high gloss, but we can also supply semi-matt, matt, structure (foam) and fluorescent materials.

Typical Applications of Polyethylene terephthalate (PET) Automotive – mirror backs – grille supports – head lamp reflectors – alternator housings Electrical applications – motor housings – electrical connectors – relays – switches – microwave oven interiors Industrial applications – furniture chair arms – pump housings – hand tools – PET bottles and containers

The excellent electrical insulation properties of PVC are well known and frequently employed in the electrical engineering industry. Moreover, most basic qualities have effective fire retardant and specially adapted properties in accordance with UL94 / V0.

PET is highly sensitive to moisture at high temperatures and exhibits excessive warpage when reinforced with glass fibers. The promotion of crystallinity is achieved through adding nucleating agents and crystal growth accelerators. Crystalline moldings exhibit high modulus, gloss, and heat distortion temperatures. Warpage is minimized by the addition of particulate fillers such as mica. When low mold temperatures are used, transparent moldings can be obtained with unfilled PETs.

Chemical and Physical Properties PET is an aromatic polyester produced from the polymerization of either terephthalic acid (TPA) or dimethyl ester terephthalic acid (DMT) and ethylene glycol (EG). The glass transition is approximately 165°C [330°F] and the material crystallizes over a temperature range from 120°C–220°C [248°F–428°F].

All of our waste is collected and shipped to a specialised recycling company. Processed plastisol cannot be reused, but solid waste can be recycled without problem and used for the production of floor mats and, for instance, flowerpots.

Polyethylene terephthalate (PET) has excellent chemical resistance and barrier properties, good strength, rigidity, fatigue endurance, and abrasion resistance.
