Plastic Compound Applications
The first step in choosing the right engineering plastic compound is ensuring you know its application so you can select the proper resin, additives, modifiers, fillers, reinforcing agents and colorants to meet your performance and cost requirements. At AKRO-PLASTIC, individuality is our speciality.
This is where we demonstrate our competitive edge: offering the highest quality products, custom-made for each of our partners. We use our knowledge of application-oriented polymer processing gained through collaboration with global companies to advance smaller customers as well.
Drinking Water Contact
The replacement of metals by engineering plastics in the drinking water and food sectors has risen steadily. A wide variety of applications are already made of plastics, such as fittings, water meter housings, filter housings and seals. Reade more here.
Metal Substitution and Weight Reduction
Driving down costs and reducing weight has been a critical objective in many industries. One of the most effective ways of achieving this is to substitute metal with plastic. Developed specifically with this in mind, AKROLOY® PA represents an ideal solution for a range of applications, including automotive, machine building and die casting, that have traditionally relied on metal.
PA 6.6 Alternatives
Due to bottelnecks in supply chain and the current price development AKRO-PLASTIC is proud to provide alternative solutions for substitution of PA 6.6 applications for every customer.
One of the new development witch regards to a PA 6.6 substitution is called AKROMID® B+. Reinforced with 50 % glass fibres, this compound achieves the same strength at 80 °C as a conditioned PA 6.6 GF50 (115 MPa breaking stress). Read more here.
Since the safe evacuation of public transportation vehicles takes a longer time, strict safety standards have to be fulfilled. AKRO-PLASTIC offers materials which are certified according to the current standards for buses (ECE 118) and trains (EN45545-2, NFPA 130).
High-performance plastics are primarily used where the highest demands are placed on the mechanics, chemical or thermal resistance or on the slippage of the products. AKROTEK® PEEK, in particular, is an excellent metal substitute for medical applications where the biocompatibility of the material is important.
Tough and Shock-Resistant
Plastic materials are often selected for applications that require toughness and impact resistance. Certain plastics, such as AKROMID® HI, have outstanding toughness, making them perfect for applications such as cable channels, cable ties, fasteners and clamps, window frames, housings and protection covers. AKRO-PLASTIC offers a broad product range using various polymers, both unreinforced and reinforced, cold and dry impact products and good batch-to-batch consistency.
Flame-retardant (FR) plastics, such as AKROMID® FR, are essential for everyday devices. Fire requires three basic elements: fuel, heat and oxygen; flame retardants use chemical reactions to moderate one or more of these attributes. Most polymers are flammable by nature, so using flame retardants affects the behaviour of the polymer. Applications include the electronic and electrical sector (plugs, terminal strips, screw connections) and the transport sector (handles, seats etc.).
Carbon Fibre Reinforcing
On applications requiring low weight, carbon fibre reinforcement is the preferred choice over glass fibre. Known as ICF, these reinforced polymer compound solutions combine high strength with low density and an attractive price. AKRO-PLASTIC’s carbon-fibre-reinforced solutions are based on polyamide 6, polyamide 6.6, PPA, aliphatic polyketone (PK) and partially aromatic PA 6.6 (AKROLOY® PA). To illustrate their performance, AKROMID® B3 ICF 40, a PA-6-based compound, achieves a tensile modulus of 30,000 MPa and a flexural strength of 320 MPa, with 1.8 % elongation at break, whereas AKROMID® A3 ICF 40, a PA-6.6-based compound, even achieves 33,000 MPa with a flexural strength of 370 MPa.
Low Moisture Absorption
For special applications, sometimes a polyamide is required that performs like other polyamides but absorbs less moisture. To meet these requirements, we developed the AKROMID® RM series. For components subject to high mechanical loads, there is AKROMID® RM-M (mechanical grades), and for visible parts such as automotive trims there is AKROMID® RM-D (design grades).
Long Glass Fibre Reinforcing
To improve strength, thermoplastics are typically reinforced with glass fibres. Under load, the forces generated are transferred from the polymer matrix to the glass fibres. Different lengths of glass fibre strand are specified demanding on the polymer and viscosity. For higher loads in particular, such as impact stress or use at higher or lower temperatures, our special compounds reinforced with long glass fibres (LGF) provide the ideal solution. The chief advantages of product lines such as AKROMID® and AKROLOY® LGF are better mechanics at increased temperatures, less creep and higher working absorption during impact stress.
