Bicycle Tire Anti-Scorching Agent CTP (PVI): Elevating Tire Quality and Rider Safety

In the bicycle manufacturing industry, the tire is the critical contact point with the ground, directly influencing riding safety and user experience. However, “scorching” (premature vulcanization) during production remains a key bottleneck, often leading to reduced yield rates and increased production costs.

The introduction of Bicycle Tire Anti-Scorching Agent CTP (PVI) provides a high-efficiency solution to this industry challenge, helping tire manufacturers significantly boost their core competitiveness.

What is CTP (PVI) Anti-Scorching Agent?

Chemical Name: N-(cyclohexylthio)phthalimide

CTP (also known as PVI) is a highly stable and efficient rubber pre-vulcanization inhibitor specifically optimized for the tire vulcanization process. Its primary function is to precisely control the induction period of the rubber vulcanization reaction. This effectively prevents the rubber from vulcanizing too early (scorching) due to heat generation during processing stages such as mixing and molding.

For bicycle tire manufacturers, the core value of CTP (PVI) is threefold:

1. Increases Yield Rates: Reduces scrap and rework caused by scorching, directly lowering production costs.
2. Optimizes Efficiency: Provides a wider safety margin for processing, making it ideal for large-scale and automated production lines.
3. Ensures Quality: Enhances critical properties like elasticity, wear resistance, and anti-aging, resulting in a safer and more comfortable ride for the end-user.

Core Advantages of Our CTP (PVI) for Bicycle Tires

Compared to traditional retarders, CTP (PVI) offers unique advantages due to its specific chemical structure and mechanism, making it irreplaceable in modern tire manufacturing:

• Precise and Efficient Anti-Scorching: CTP (PVI) rapidly interacts with the accelerator in the sulfur system to inhibit early cross-linking. Even under harsh conditions—such as high-temperature mixing or long storage periods—it provides a sufficient safety buffer (scorch delay), adapting to various tire specifications and materials.
• Superior Compatibility: This product is highly compatible with common tire rubbers (Natural Rubber, SBR, NBR) and various additives (vulcanizing agents, fillers). It prevents scorching without altering the final vulcanization characteristics or negatively impacting core performance metrics like hardness, tensile strength, or tear resistance.
• Low Dosage, High Cost-Effectiveness: Due to its high activity, the recommended dosage is only 0.1-0.5 phr (parts per hundred rubber). Compared to traditional anti-scorching agents, usage is reduced by over 30%, significantly lowering raw material costs while maximizing protection.
• Eco-Friendly & Compliant: Our CTP (PVI) is free from heavy metals and harmful volatiles. It complies with major international environmental standards, including EU REACH and US FDA regulations, as well as domestic safety norms. This supports green manufacturing and mitigates compliance risks.
• Versatile Application: Whether producing tires for mountain bikes (MTB), road bikes, city commuters, or children’s bikes—and whether for pneumatic or solid tires—CTP (PVI) performs stably across diverse environments (low temp, high temp, or high humidity).

Application Scenarios: Covering the Full Production Chain

Bicycle Tire Anti-Scorching Agent CTP (PVI) is essential across the critical stages of tire manufacturing:

• Rubber Mixing: Prevents scorching caused by friction heat generation during high-speed mixing.
• Tire Molding: Ensures rubber remains pliable during the molding process, guaranteeing precision and reducing defects.
• Storage: Extends the storage life of uncured rubber compounds (semi-finished products), reducing inventory loss.
• Pre-Vulcanization Treatment: Provides precise control over temperature and time parameters before final curing.

Note: It is also widely used in tire retreading and the production of rubber accessories such as tire valves and seals.
