Basic knowledge and unique advantages of low-freeness TDI trimer

As a high-tech chemical product, the basic structure of low-freeness TDI trimer is mainly formed by diisocyanate (TDI) through a special polymerization process. TDI itself is an organic compound containing two isocyanate groups, while trimers connect multiple TDI molecules to each other through the action of a specific catalyst to form a more stable macromolecular structure. This polymerization process not only improves the overall performance of the material, but also significantly reduces the residual amount of unreacted TDI monomers, thereby improving the environmental protection and safety of the product.

Chemical composition and structural characteristics

The core component of the low-freeness TDI trimer is the TDI molecule, but after polymerization, its chemical structure undergoes significant changes. Traditional TDI monomers are prone to evaporation and may cause harm to the human body, while trimer forms greatly limit thisVolatility makes the material more stable and easy to process. In addition, complex crosslinking network structures are formed inside the trimer, which imparts excellent mechanical strength and elastic recovery capabilities to the material. Simply put, it is like bonding a pile of loose sand into a solid piece of stone with glue. The low-freeness TDI trimer achieves qualitative change from a single molecule to a composite material through the recombination of chemical bonds.

Unique Performance Analysis

1. High wear resistance
   The low-freeness TDI trimer has extremely high wear resistance due to its unique cross-linking structure. The surface can be kept intact and undamaged even under high frequency friction or impact conditions. This makes it very suitable for use in tracks, courts and other venues that require frequent use. Just imagine, if the track surface wears rapidly due to frequent use, it will not only affect the athlete's performance, but may also lead to slips or other safety hazards. The existence of low-free TDI trimers is like covering these sites with an indestructible protective clothing.

2. Excellent UV resistance
   Long-term exposure to sunlight will cause the normal material to age or even crack, but low-freeness TDI trimers can resist ultraviolet erosion. This is because its molecular structure contains special UV absorbing groups, which can effectively shield the influence of harmful light. This characteristic is particularly important for outdoor sports venues. Whether it is the scorching summer or the windy frost, rainy and snowy winter, the low-free TDI trimer can ensure that the venue facilities are always in good condition.

3. Environmental and low toxicity
   Compared with other TDI-containing materials, the major advantage of low freedom TDI trimers is its extremely low free TDI content. Unreacted TDI monomers emit a pungent odor and may have a irritating effect on the body's respiratory tract. The low-freeness TDI trimer controls the content of this harmful substance to an extremely low level through advanced production processes, which complies with international environmental protection standards. Therefore, it is not only friendly to construction workers, but also safer to the audience and athletes in the venue.

4. Elastic Resilience
   In stadiums, flexibility is a key indicator. For example, track and field tracks require a certain buffering effect to reduce the pressure on the athlete's joints, while basketball courts require sufficient rebound to ensure the normal movement of the ball. Low-free TDI trimers can meet these diverse needs with their excellent elastic recovery capabilities. Imagine that when you jump, the ground under your feet can rebound in time instead of getting stuck in it, this experience will undoubtedly make people feel more comfortable and at ease.

5. Waterproofing
   Moisture permeability is a common problem faced by many building materials, especially in rainy areas. However, low-freeness TDI trimers have natural waterproof properties and can maintain stable performance in humid environments. This means that even when hit by heavy rain, there will be no accumulation of water or leakage, which will extend the service life of the facility.
