In the world of outdoor recreational equipment, modular pump tracks have become a favorite for BMX riders, skateboarders, and cyclists seeking thrilling, low-maintenance setups. At Ultra Pump Track, we prioritize innovation and quality, which is why our tracks are crafted from high-performance Linear Low Density Polyethylene (LLDPE) resin. But we often hear concerns from customers about using plastic materials outdoors. Questions like “Will it warp in the sun?” or “Is it durable in cold weather?” are common—and completely valid. In this blog post, we’ll dive deep into the science behind our LLDPE material, answer those burning questions, and explain why it’s the superior choice for your next pump track.

Common Concerns About Plastic Pump Tracks

When customers learn that our modular pump tracks are made from plastic, these are the top questions that arise:

1. Will it deform in sunlight? Does plastic soften when heated?Worries about heat affecting performance are understandable, especially in hot climates.
2. Can the track withstand cold weather? Does plastic become brittle in the cold?Freezing temperatures can make some materials fragile, raising safety concerns.
3. Will the color fade under UV exposure?Outdoor equipment needs to maintain its vibrancy over time.
4. Is a single plastic module lightweight? Does the assembled track need to be fixed to the ground?Stability is key for safe, high-speed riding.
5. Is the track made from high-quality raw materials? Does it have any odor?Safety and environmental considerations are paramount, especially for kids’ play areas.
6. What are the advantages compared to wooden tracks?Many wonder if plastic truly outshines traditional wood in outdoor settings.

Let’s address these head-on with a closer look at our material of choice: LLDPE.

Introducing LLDPE: The High-Performance Material Behind Our Pump Tracks

Our modular pump tracks are made from LLDPE, or Linear Low Density Polyethylene Resin, specifically the InnoPlus LL9450U and LL9450UP grades. These are butene co-monomer based resins designed for rotational molding applications. What sets them apart? They’re stabilized, offering an excellent balance of flow, stiffness, impact strength, toughness, and color stability. The LL9450UP variant comes in powder form for precise manufacturing.

Typical Applications

InnoPlus LL9450U and LL9450UP are versatile and ideal for:

• General molding
• Toys and playground equipment
• Outdoor storage containers
• Water tanks

This makes them perfect for durable, weather-resistant products like our pump tracks.

Key Properties

Here’s a breakdown of the material’s typical properties, tested to industry standards:

FDA Statement :

For added peace of mind, our LLDPE under the InnoPlus brand complies with U.S. FDA 21 CFR 177.1520 regulations for polyethylene used in food-contact articles (except those for cooking). This underscores its safety for everyday use, including around children.

These specs aren’t just numbers—they translate to real-world performance that tackles your concerns directly.

Answering Your Top Questions About LLDPE Pump Tracks

Let’s use the material’s properties to respond to each common query:

Will it deform in sunlight? Does plastic soften when heated?

No need to worry! The Vicat Softening Point is a robust 114°C. Even in extreme heat—like Riyadh, Saudi Arabia, where summer highs average over 40°C and can spike to 50°C—our tracks stay firm. The surface won’t soften or deform, ensuring consistent performance for riders.

Can the track withstand cold weather? Does plastic become brittle in the cold?

Absolutely. With a Brittleness Temperature below -70°C, our LLDPE remains tough in freezing conditions. Take Yakutsk, Russia—the world’s coldest inhabited city, with January averages at -46°C. Our tracks won’t crack or become brittle, maintaining safety and durability year-round. Mechanical properties like high elongation (1000%) and flexural modulus (600 MPa) further highlight its toughness.

Will the color fade under UV exposure?

We’ve got you covered. Our material includes UV stabilizers, which prevent degradation from sunlight. Lab tests show significant improvements in light resistance, allowing us to confidently offer a 5-year warranty. Your pump track will keep its vibrant colors, looking fresh season after season.

Is a single plastic module lightweight? Does the assembled track need to be fixed to the ground?

Modules vary in thickness from 8mm to 10mm depending on the section, with individual weights ranging from 45kg to 60kg—easy for two adults to handle during setup. For a full 40-module track, the total weight hits around 1,800kg, providing rock-solid stability on the ground without any need for anchoring. It’s modular design at its best: portable yet secure.

Is the track made from high-quality raw materials? Does it have any odor?

Yes we source premium raw materials from top chemical manufacturers. There’s no unpleasant odor, making it ideal for kids’ play. Combined with FDA compliance and superior mechanical strength, you can trust it’s safe and reliable for family fun.

What are the advantages compared to wooden tracks?

We’ve produced wooden tracks ourselves—they work indoors, but outdoors? Not so much. Even with waterproofing on surfaces and sides, wooden bases struggle with moisture. In rainy regions, repeated soaking and drying cause warping and structural damage. Our LLDPE pump tracks eliminate these issues: they’re fully waterproof, UV-resistant, and maintenance-free. Plus, they offer better impact absorption, reducing injury risks, and easier assembly without the need for tools.

Why LLDPE Makes Ultra Pump Tracks the Smart Choice

Choosing LLDPE for our modular pump tracks isn’t just about cost—it’s about delivering unmatched durability, safety, and longevity. This material withstands extreme conditions, from scorching deserts above 50°C to icy tundras below -40°C, without deforming or cracking. Unlike wood, which warps in rain or requires constant maintenance, LLDPE offers seamless, worry-free use with minimal upkeep.

Its superior impact strength absorbs shocks, reducing injury risks in parks, schools, or backyards. UV stabilizers preserve colors, backed by a 5-year warranty, while FDA compliance ensures safety—no odors or toxins. Sourced from premium manufacturers, LLDPE promotes sustainability and quality, turning tracks into reliable investments for endless fun and active lifestyles.
