Types of plastic for building products can look similar, but they rarely behave the same in real use. Many people assume “plastic is plastic”. However, plastics form a whole family of materials, and each one responds differently to impact, weather, temperature and long-term wear.
Because of that, material choice affects durability, customer satisfaction and returns. It also explains why we focus on practical guidance, product knowledge matters in building products when performance sits on the line.
In this post, we’ll break down the main plastic types used in building products — including LDPE, used in Rhino Flexi Tubs — and show how to choose the right one for the job.
Types of plastic for building products: the properties that change performance
When you compare types of plastic for building products, focus on a few core properties:
Strength vs flexibility: does it hold shape or flex and recover?
Impact resistance: does it crack or absorb knocks?
UV and weathering: does sunlight make it brittle over time?
Temperature performance: does it change behaviour in cold or heat?
Moisture and chemical resistance: does it degrade or lose strength?
Long-term fatigue: does repeated stress weaken it?
Material choice is step one. Next, design and construction choices also matter. That’s why product construction impacts durability in the real world.
Common types of plastic for building products and where they work best
Below are the most common types of plastic for building products, explained without the jargon.
Polypropylene (PP): a tough all-rounder
PP gives you a strong balance of toughness, low weight and chemical resistance. As a result, it suits many everyday components where durability matters.
ABS: rigid, impact-resistant and stable
ABS holds shape well and gives a solid feel. Therefore, it works well when stiffness, impact performance and surface finish matter.
Polycarbonate (PC): high toughness under impact
PC handles heavy knocks and stays strong. For that reason, manufacturers often choose it where impact resistance and performance come first.
Nylon (PA): strong, wear-resistant and durable under stress
Nylon performs well under mechanical stress and friction. Consequently, it suits parts that face repeated loading or wear.
LDPE: flexible, impact-resistant and built for repeated handling
LDPE behaves differently because it flexes and absorbs impact rather than cracking. That makes it ideal for products designed for repeated drops, bends and heavy-duty use.
Rhino Flexi Tubs rely on that behaviour. They flex, recover and keep going through the kind of handling that would crack a more brittle plastic. It’s also why Rhino is trusted by pros and merchants for trade use.
If you want proof from the field, the customer reviews from trades and installers tell the story clearly.
Why the wrong plastic choice creates returns, complaints and wasted time
When you choose the wrong plastic, the failure mode shows up fast. For example, you might see cracking in cold weather, warping under load, or premature wear.
Merchants then deal with returns and credits. Installers face rework and callbacks. Buyers get a product line that quietly creates friction.
That’s the practical side of the hidden cost of product failure on building projects.
How to choose the right type of plastic for building products
You don’t need to be a polymer expert. Instead, match the plastic to the job.
1) Start with the environment
Consider indoor vs outdoor use, UV exposure, damp areas, and temperature swings. Then choose a plastic that can handle those conditions over time.
2) Think about how people will handle it
Ask whether it will take knocks, drops, flexing, stacking or heavy loads. If it will, prioritise impact resistance and fatigue performance.
3) Decide what matters most: stiffness or flexibility
Some products need rigidity to hold shape. Others need flexibility to avoid cracking. Therefore, the “best” plastic depends on the outcome you want.
4) Ask “why this plastic?” not just “what plastic?”
A good supplier should explain why the material fits the application, what it handles well, and where its limits sit.
Stadium’s approach to types of plastic for building products
At Stadium, we use manufacturing expertise to choose materials that match real-world use. We focus on consistent performance because fewer failures means fewer returns, fewer callbacks and stronger trust over time.

FAQs for Types of Plastic for Building Products
1) Do types of plastic for building products really matter?
Yes. Different plastics vary widely in rigidity, flexibility, impact resistance and weathering performance.
2) What plastic works best for flexibility and impact resistance?
LDPE is a strong example because it flexes and absorbs impact, which is why Rhino Flexi Tubs use it.
3) Why do some plastics crack in cold weather?
Some plastics become more brittle at low temperatures. If impact happens then, cracks become more likely.
4) What’s the difference between PP, ABS and PC?
PP is a tough all-rounder, ABS is rigid with a solid finish, and PC prioritises high impact resistance and toughness.
5) Can Stadium advise on selecting the right product/material?
Yes — our team can help match products to real-world performance requirements.
