Plastic products are made from polymer mixed with a complex blend of materials known collectively as additives. With additives, plastics can be made safer, cleaner, tougher and more colorful. We have a wide range of additives in stock.
One way to improve the performance characteristics of plastic products is to compound resins with additives and fillers. Additives help inhibit factors such as heat, chemicals, or light. There are thousands of additives/fillers on the market today. Below are some of the most common additives used in our manufacturing.
Used to control the degradation of products due to air exposure.
Used to minimize static electricity. These types of additives can be mixed with the resin or applied to the surface of the product. Antistatic additives are common to a wide variety of products ranging from cosmetics to industrial goods to sensitive electronic parts.
Used for the economical and even application of polyurethane paints to consumer goods such as automobiles, bicycles, and others.
Used to increase strength and stiffness. The most common type of fibers added for strength would be carbon and glass. Glass-reinforced plastic is more commonly known and marketed as fiberglass.
Used to provide special properties for certain applications.
Added to make products softer and more flexible. Some plasticizers evaporate and tend to concentrate in an enclosed space; the “new car smell” is caused mostly by plasticizers evaporating from the car interior.
Used for easier molding or for increased adhesion and viscosity of the molded parts.
Used for the protection of the resin’s mechanical properties by absorbing selective UV rays resulting in less degradation.
An inexpensive substance such as wood, metal, glass or clay that is added to plastics in very small particles to decrease cost, improve hardness, stiffness, and impact strength.
Flame retardants / Smoke suppressants
A variety of chemicals that can be added to resins to eliminate its tendency to burn. For polyethylene and similar resins, chemicals such as antimony trioxide and chlorinated paraffin are useful.
Used to add color, special effects, or patterns to plastic products.
In-mould labelling with special properties may inhibit oxygen transport and transmittance of UV-rays (as well as visible light).
Based on information from an IML-supplier, labels with oxygen transmission rates (measured at 23°C, approx. 65% RH and against 100% oxygen) between 0,3 and 2,0 cc/m²/day atmosphere are available. Transparent IML-labels yielding less than 1% transmission of UV light (200 – 380 nm). The label will have to cover the surface completely, as any uncovered area will not have barrier properties. This is limiting the viable design/shape options.
Tubes are manufactured using laminate feed stock with a poly-foil-poly structure that has polyethylene on either side of a thin gauge of foil. Laminate tubes are produced from a multilayer laminate foil, either with aluminium or plastic (EVOH) barrier, inhibiting oxygen transport and transmittance of UV-rays.
Laminate foil has the ideal synthesis between the barrier effect of aluminium and the feel and the flexibility of plastic.
ABL (Aluminium Barrier Laminate) or PBL (Plastic Barrier Laminate) tubes are a light, hygienic and safe form of packaging that prevents leakage, provides UV and O2 protection and can also hold more aggressive products.
