A versatile thermoplastic with an exceptional balance of chemical resistance, fatigue strength, and processability — now available in fully recycled grades that match virgin performance.

Polypropylene is one of the most widely used thermoplastics in the world, valued for its low density, excellent chemical resistance, and outstanding fatigue performance. It processes cleanly via injection moulding and can be formulated with mineral fillers, impact modifiers, and UV stabilisers to meet demanding application requirements.

Our recycled PP compounds are sourced from controlled post-industrial and post-consumer waste streams, reprocessed under strict quality control, and supplied as consistent, specification-grade pellet — ready for your injection moulding line. Every grade we supply meets your mechanical, thermal, and aesthetic targets while helping you achieve recycled content commitments.

From black pellet feedstock for non-appearance-critical parts to mineral-filled compounds for structural applications, we supply the full spectrum of recycled polypropylene grades — all backed by batch-level QC certification and full traceability.

Key Properties

Performance Characteristics

Recycled polypropylene delivers a compelling balance of mechanical, chemical, and thermal properties — making it suitable for a wide range of injection moulded parts.

Chemical Resistance

Excellent

Outstanding resistance to acids, alkalis, and most organic solvents. Suitable for containers, fittings, and components exposed to aggressive chemical environments.

Fatigue Resistance

Excellent

Exceptional resistance to repeated flexing and stress cycling. Polypropylene is the material of choice for living hinges and components subject to repetitive mechanical loads.

Impact Strength

Good — High

Good impact resistance at room temperature, significantly enhanced with copolymer grades or impact modifier additives. Some reduction at sub-zero temperatures.

Stiffness

Moderate — High

Good inherent stiffness that can be significantly increased with mineral fillers such as talc or calcium carbonate — ideal for structural and semi-structural mouldings.

Heat Resistance

Good

Melting point of 130–171°C depending on grade. Higher than polyethylene, making PP suitable for applications requiring moderate heat resistance and hot-fill capability.

Low Density

Excellent

At 0.9 g/cm³, polypropylene is the lightest of the major commodity thermoplastics — reducing part weight, lowering material costs, and improving transport efficiency.

Applications

Where Recycled PP Performs

From construction fittings to industrial containers, recycled polypropylene delivers reliable performance across a broad range of injection moulded applications.

🏗️

Construction Fittings

Pipe clips, junction boxes, conduit fittings, and general construction fixings. Impact-modified grades handle site conditions and temperature variation.

📦

Industrial Containers

Storage bins, crates, pallets, and heavy-duty containers. PP's chemical resistance and fatigue performance make it ideal for reusable industrial packaging.

🔧

Housings & Enclosures

Equipment housings, junction boxes, meter enclosures, and protective covers. Mineral-filled grades provide the stiffness and dimensional stability required.

🚗

Automotive Components

Under-bonnet components, interior trim, battery covers, and wheel arch liners. Talc-filled PP delivers the stiffness-to-weight ratio the automotive sector demands.

🌿

Garden & Outdoor

Planters, garden furniture components, compost bins, and outdoor storage. UV-stabilised grades resist degradation from prolonged sunlight exposure.

⚙️

General Industrial

Caps, closures, handles, brackets, and functional components across every manufacturing sector. PP's versatility makes it the default choice for general-purpose mouldings.

Compatible Methods

Injection Moulding

Primary processing method. All grades optimised for consistent fill, cycle time, and surface finish on standard injection moulding equipment.

Multi-Component

Compatible with overmoulding and multi-shot processes. Bond strength and shrinkage behaviour characterised for common material pairings.

High-Speed Moulding

High-MFI grades available for thin-wall and high-speed moulding applications where fast cycle times and complete cavity fill are critical.

Structural Foam

Filled grades suitable for structural foam moulding — producing lightweight parts with solid skins and foamed cores for large, stiff components.

Why Recycled PP

The Advantages of Choosing Recycled

01

Circular Economy

Every kilogram of recycled PP diverts waste from landfill and reduces demand for virgin polymer production — supporting your sustainability targets without compromising part performance.

02

Cost Efficiency

Recycled PP compounds typically offer significant cost advantages over virgin equivalents — reducing your material spend while maintaining the mechanical and processing properties your line requires.

03

Lower Carbon Footprint

Recycled polypropylene production generates substantially lower CO₂ emissions than virgin polymer manufacturing — helping you demonstrate measurable environmental impact to customers and regulators.

04

Regulatory Readiness

Incoming legislation increasingly mandates recycled content in manufactured products. Switching to recycled PP now positions your supply chain ahead of regulatory requirements.

05

Consistent Quality

Our recycled PP compounds are reprocessed under strict QC control — delivering the batch-to-batch consistency your injection moulding line demands, with full traceability and test certification.

06

Supply Security

Diversifying your polymer supply to include recycled feedstock reduces dependence on volatile virgin resin markets — providing greater price stability and supply resilience.
