Tractor Tire Anti-Scorching Agent CTP (PVI): The Key to Efficient Production & Superior Quality

Discover how Anti-scorching Agent CTP (PVI) optimizes tractor tire manufacturing. Prevent scorching, extend storage life, and improve product quality with our high-purity rubber additives.

In the field of tractor tire manufacturing, the issue of “scorching” (premature vulcanization) has long been a critical pain point that restricts production efficiency and affects product quality. Scorching not only leads to the scrapping of semi-finished compounds—driving up costs—but also severely compromises the mechanical properties and service life of the final tire, causing significant economic losses.

The Tractor Tire Anti-scorching Agent CTP (PVI) offers a high-efficiency, reliable solution to this industry challenge. As a core auxiliary agent in tire production, CTP (PVI) has become the preferred choice for leading tire manufacturers due to its exceptional anti-scorching performance and chemical stability.

I. In-Depth Analysis: Core Advantages of CTP (PVI) for Tractor Tires

Anti-scorching Agent CTP (PVI) (Chemical Name: N-(cyclohexylthio)phthalimide) is a highly effective pre-vulcanization inhibitor. It is specifically developed to address the high-temperature, high-pressure, and long-vulcanization characteristics of tractor tire production. Its four core advantages include:

1. Superior Anti-Scorching Performance to Eliminate Waste

CTP (PVI) effectively prolongs the scorch time of rubber compounds.

Proven Results: Adding 0.3%-0.5% of CTP (PVI) to standard tractor tire formulas extends the scorch time by 40%-60%.
Operational Benefits: This provides an ample processing window for mixing, molding, and other pre-processing steps.
High-Temperature Resilience: Even in summer environments exceeding 35°C or during production pauses longer than 4 hours, it prevents the compound from hardening prematurely.
Cost Reduction: It helps manufacturers keep the semi-finished scrap rate below 0.5%, significantly reducing waste and ensuring production continuity.

2. Stable Vulcanization for Guaranteed Tire Quality

Unlike ordinary retarders, CTP (PVI) prevents scorching without interfering with the normal vulcanization process or degrading the mechanical properties of the vulcanized rubber.

Third-Party Testing Data: Tractor tire compounds containing CTP (PVI) exhibit:
- Tensile Strength: >18 MPa
- Tear Strength: ≥50 kN/m
- Wear Resistance: Improved by ~15%
Performance: The tires maintain stable hardness, elasticity, and durability, ensuring safety and longevity under complex operating conditions (e.g., muddy roads, heavy-load operations).

3. High Compatibility with Various Formulas

Our CTP (PVI) boasts excellent compatibility. It is suitable for:

Rubber Bases: Natural Rubber (NR), Styrene-Butadiene Rubber (SBR), Nitrile Rubber (NBR), and more.
Systems: Various vulcanization systems and accelerator formulations.
Ease of Use: It can be added directly without requiring significant changes to existing production processes, minimizing re-engineering costs.

4. Eco-Friendly & Compliant with Industry Standards

Safety: The product strictly follows environmental standards, containing no harmful heavy metals or volatile toxic substances.
Worker Health: No toxic gases or pollutants are generated during production.
Certification: Meets domestic and international tire industry environmental certifications, helping enterprises overcome green trade barriers.

II. Precision Application: When to Use CTP (PVI)

Thanks to its unique performance, CTP (PVI) is widely used in various tractor tire production processes, specifically optimized for:

Heavy-Duty Tractor Tires: Heavy-load tires require complex formulas and long vulcanization times. CTP (PVI) prevents scorching during the early stages of molding and curing.Case Study: A large agricultural machinery tire manufacturer increased their semi-finished pass rate from 92% to 99.3% and boosted efficiency by 20% after adopting our PVI.
Agricultural Specialty Tires: Agricultural environments are harsh. CTP (PVI) ensures stable vulcanization, improving the tire’s tear resistance and adaptability to rugged terrain.
High-Temperature Season Production: Summer heat significantly increases scorching risks.Data: Manufacturers in southern regions using CTP (PVI) reported a 12%-18% increase in qualified production rates during summer compared to those who did not, effectively mitigating seasonal fluctuations.
Tire Retreading & Reclaimed Rubber: In retreading and reclaimed rubber processing, CTP (PVI) prevents premature vulcanization during mixing, enhancing the quality and lifespan of the retreaded product.
