Why Material Selection Is Important
Selecting the right thermoplastic material is one of the most important decisions in the product development process. The material you choose can influence everything from performance and appearance to durability, manufacturability and overall project cost.
At J & A Kay, we work with customers across a range of sectors to identify the most suitable materials for their application, ensuring components deliver the performance required throughout their service life.
Understanding Your Application
Before selecting a material, it’s essential to consider how the component will be used. Factors such as operating environment, impact resistance, exposure to chemicals, UV stability, temperature requirements, budget, volume and aesthetic finish can all influence the most appropriate choice.
Choosing the right material early in the design process can help avoid costly redesigns while improving product performance and longevity.
ABS: The Versatile All-Rounder
ABS (Acrylonitrile Butadiene Styrene) is one of the most widely used thermoplastics in thermoforming. It offers an excellent balance of strength, impact resistance, appearance and cost-effectiveness.
Common applications include:
• Vehicle interior components
• Equipment housings
• Machine guards
• Industrial enclosures
Its versatility makes ABS a popular choice across many sectors.
Polycarbonate: When Strength Matters
For applications requiring exceptional toughness and impact resistance, polycarbonate is often the ideal solution.
Polycarbonate provides:
• High impact strength
• Excellent durability
• Good temperature resistance
• Optical clarity where required
This makes it suitable for demanding industrial, transport and protective applications.
Acrylic: Outstanding Visual Appeal
Where appearance is a priority, acrylic can offer excellent optical properties and surface finish.
Benefits include:
• High gloss appearance
• Excellent clarity
• UV resistance
• Strong weathering performance
Acrylic is commonly used for displays, covers and applications where aesthetics are particularly important.
Polypropylene (PP): Lightweight and Chemical Resistant
Polypropylene is a highly versatile material known for its excellent chemical resistance, durability and lightweight properties. It performs particularly well in environments where exposure to moisture, chemicals or repeated use is a consideration.
Benefits include:
• Excellent chemical resistance
• Lightweight and durable
• Good fatigue resistance
• Suitable for demanding industrial applications
Common applications include industrial components, tanks, trays, covers and protective housings where robustness and longevity are essential.
HDPE: Tough and Hard-Wearing
High-Density Polyethylene (HDPE) is valued for its toughness, impact resistance and ability to withstand harsh environments. It offers excellent resistance to chemicals and moisture, making it ideal for both indoor and outdoor applications.
Benefits include:
• High impact strength
• Excellent chemical resistance
• Moisture and weather resistant
• Durable and long-lasting
HDPE is frequently used for industrial equipment, protective covers, ducts, containers and components that require dependable performance in challenging conditions.
HIPS: Cost-Effective and Easy to Form
High Impact Polystyrene (HIPS) is a popular choice for applications where ease of fabrication, good surface finish and cost efficiency are important. It thermoforms exceptionally well and provides a practical solution for a wide range of products.
Benefits include:
• Excellent formability
• Smooth surface finish
• Lightweight
• Cost-effective material option
HIPS is commonly used for product housings, point-of-sale displays, packaging applications, prototypes and components where aesthetic appearance and economical production are key considerations.
Other plastics we use include: PVC, PETG, TPU, Boltaron, Kydex, PVC Foam and more.
