Introduction
The rubber industry faces mounting pressures from rising raw material costs, stringent environmental regulations, and increasing demand for high-performance materials. Traditional fillers like carbon black and calcium carbonate struggle to meet modern requirements for strength, air tightness, and aging resistance.
As a leading Rubber Reinforcing Filler Manufacturers China, we introduce GreenThinking® PF87 – a revolutionary flake-shaped nano reinforcing filler that addresses these challenges through advanced material science. This article examines industry pain points and demonstrates how PF87 delivers superior performance while reducing costs.


Current Challenges in the Rubber Industry
- Performance Limitations of Conventional Fillers
- Calcium carbonate offers poor reinforcement (tear strength <24 KN/m)
- Carbon black improves strength but increases hardness and processing difficulty
- Silica requires coupling agents and complex processing
- Sustainability and Cost Pressures
Global regulations (REACH, EPA) demand eco-friendly solutions, while volatile raw material prices require cost-effective alternatives like high strength filler for rubber. - Processing Difficulties
Many fillers reduce scorch time (T10 <2 mins) and increase viscosity (ML >2.0 dN.m), compromising production efficiency.
PF87: Technical Advantages and Solutions
- Superior Reinforcement Performance
Test data shows:- 300% modulus: 4.8 MPa (PF87) vs 4.38 MPa (calcium carbonate)
- Tear strength: 25 KN/m vs 24 KN/m in control formulas
- Aging resistance: 85% tensile strength retention after 48h@100°C
- Exceptional Air Tightness
The nano-flake structure creates tortuous diffusion paths, making it an ideal filler for air tight rubber products:- Gas permeability coefficient: 3.413E-16 cm³·cm/cm²·s·Pa (50phr PF87)
- 26% improvement vs calcium carbonate-filled compounds

- Cost Optimization Through High Loading
As a rubber functional filler, PF87 enables:- 30-150phr loading capacity
- 10-15% material cost reduction vs carbon black formulations
- Controlled hardness increase (+1° Shore A per 8-10phr)
- Enhanced Processing Characteristics
- Low Mooney viscosity (ML 1.28 dN.m)
- Extended scorch time (T10 1:59)
- Excellent flowability for complex extrusions
- Eco-Friendly Multi-Functionality
- Non-toxic, heavy metal-free composition
- Compatible with NR, SBR, IIR, and plastics
- Reduces energy consumption during processing
Industry Applications
