1. PVC adhesive overview
PVC adhesive, or polyvinyl chloride adhesive, is a widely used adhesive material in a variety of industrial and commercial fields. Its main component is polyvinyl chloride (PVC), which is favored for its excellent adhesion, durability and cost-effectiveness. PVC adhesive is widely used in multiple industries, including but not limited to electronics, aerospace, communications industry and automotive industry. Among them, Pvc Pipe Adhesive is often used to connect PVC pipes to ensure a strong bond between pipes; Liquid Pvc Vinyl Adhesive, as a liquid form of polyvinyl chloride vinyl adhesive, can be used in some scenes that require fine coating and bonding due to its good fluidity and permeability.
2. Types of PVC adhesives
1)Solvent-based PVC adhesives
Solvent-based PVC adhesives are one of the most common types. They work by dissolving the surface of the PVC material and forming a strong bond when they resolidify. These adhesives usually have a fast curing time and provide a high-strength bond. Some solvent-based PVC adhesives also include 2-Part PVC Adhesives, which can achieve specific performance requirements, such as stronger adhesion or faster curing speed, by mixing two different components.
2) Hot Melt Adhesives
Hot melt adhesives are a type of thermoplastic adhesive that is applied in a molten state and hardens after cooling. They are favored for their fast setting time and strong initial adhesion. However, they may not provide the same long-term durability as solvent-based adhesives.
3) Water-based PVC Adhesives
Water-based PVC adhesives are an environmentally friendly alternative to solvent-based adhesives. They use water as a carrier for the adhesive components and generally require longer drying times. While they are not as aggressive as solvent-based adhesives, they can still provide effective bonding for many applications.
4) UV Curing Adhesives
UV-cured adhesives harden when exposed to ultraviolet light. They are often used in applications that require precise control of the curing process and are viable for UV exposure.

6. Current status and development trend of PVC Adhesive in China
6.1. Current market status
1) Weak demand and structural adjustment
As an important supporting material for PVC downstream applications, the demand for PVC Adhesive (PVC Adhesive) is highly correlated with the overall PVC market. In 2024, affected by the continued downturn in the real estate industry (65% of PVC downstream demand depends on the real estate sector), the consumption of PVC in traditional building materials, pipes and other fields has shrunk significantly, indirectly leading to pressure on the demand for PVC adhesives. But at the same time, the demand for PVC in emerging fields such as packaging, medical care, and cables is showing an upward trend, which may provide local growth points for the adhesive market.
2) Supply-side capacity expansion and cost pressure
In 2024, the total PVC production capacity will reach 27.54 million tons/year, and the output will increase by 2.67% year-on-year to 23.4398 million tons. In order to maintain the comprehensive profit of chlor-alkali, enterprises will maintain a high operating rate, resulting in sufficient supply of raw materials, but intensified market competition. The production cost of PVC adhesives may be affected by the price fluctuations of PVC raw materials. The average price of PVC in 2024 fluctuated and fell by 12.13%, providing adhesive companies with room for cost optimization, but they need to cope with the challenge of downstream demand differentiation.
3) Inventory and export pressure
Midstream inventory remains high. In 2024, the overall PVC industry will be in oversupply. The export market is hindered by policy risks such as India's anti-dumping investigation (India accounts for 50% of China's PVC exports), which may be further transmitted to the adhesive export chain.
6.2. Development trend
1) Emerging application areas drive demand growth
With the transformation of PVC consumption structure, the demand for traditional building materials is gradually replaced by new building materials, medical packaging, cables, etc. The demand for environmentally friendly PVC adhesives in the medical field may increase, driving companies to develop low-VOC (volatile organic compounds) or bio-based products. In addition, innovative applications in new energy cables, lightweight automobiles and other fields may become growth engines.
2) Capacity expansion and technology upgrade
In 2025, China plans to add 2.5 million tons of PVC capacity (mainly ethylene method), of which the new capacity in East China and South China will enhance regional supply capacity, which may promote the concentration of adhesive production in the direction of integration and low cost. At the same time, the popularization of ethylene process may promote the optimization of adhesive performance.
3) Stricter policies and environmental protection requirements
The tightening of global supervision on environmentally friendly materials may accelerate technological innovation in the PVC adhesive industry. For example, the EU REACH regulation's restrictions on chemicals and China's "dual carbon" goals will promote companies to develop water-based or solvent-free adhesives and reduce dependence on traditional solvents.
