Comparative Evaluation of Three Crosslinking Agents Used in Polyurethanes
What is Curing Agent or Hardener? Curing agent (sometimes also referred to as hardener ) is a chemical substance added to coatings, adhesives, resins or other materials to promote polymerization or cross-linking reactions in them and change from liquid/paste form into solid form for curing purposes – creating curing substances with specific physical and chemical […]
Utilizing Anti-Hydrolysis Agents in Thermoplastic Polyurethane Films: Introducing Innovations that Reduce Hydrolysis
Introduction Within material science, thermoplastic polyurethane (TPU) films have emerged as an innovative solution, boasting impressive properties. Their durability and performance characteristics have only increased with anti-hydrolysis agents added as anti-hydrolysis agents further strengthen them extending their use across applications. This article delves deeper into their properties, applications and transformative potential within TPU film applications. […]
Application of carbodiimide as an anti-hydrolysis agent for bio-based TPU
Bio-based thermoplastic Polyurethane (TPU), also named bio-based polyurethane, has gained a lot of attention in recent years. However, it is possible that ester bond hydrolysis could occur during its usage. Hydrolysis means the chemical chain is broken under the influence of water. This problem can be solved by adding carbodiimide. We will share this information […]
A detailed look into the hydrolysis of polymers: Profound focus on Urethane Hydrolysis
Basic Hydrolysis of polymers The hydrolysis of polymers involves a chemical reaction in which water interacts directly with the polymer. This interaction breaks the bonds that hold it together, and reduces the polymer into monomers or smaller polymer chains called oligomers. This is the opposite of polymerization – the process that creates polymers by combining […]
Application of Anti-Hydrolysis Agents in Recycled PET
What is polyester? Polyeseter is made from a polymer that has a variety of applications and types. It is produced by esterification,the chemical reaction in which an alcohol reacts with an acid to form an ester. Polyethylene terephthalate (PET) is probably is probably the most common polyester. Polyester is also the main component of synthetic […]
Linking Function and Beauty: The Magic of Carbodiimide in Polyester Zippers
In life, we often overlook the small but vital details. Take zippers for example, their existence and application have long been deeply rooted in our daily lives. In our clothes, shoes, hats, bags and even camping equipment, zipper is an important part, and sometimes it is even the key to measure the quality of a […]
PLA filament: how to make it more durable?
What is PLA filament material? PLA filament, also known as polylactic acid filament, is a 3D printing material made from polylactic acid (PLA). The raw material, PLA, is a biodegradable plastic derived from an organic acid called lactic acid, which is usually obtained by fermenting starch from plants. As such, PLA filament is an environmentally […]
Preventing Cracking in PU Leather: Techniques and Solutions
What is PU? Polyurethane (PU) is a polymer material whose molecules contain repeating units of ether or ester bonds. PU has a wide range of excellent properties, including abrasion resistance, oil resistance, solvent resistance, and good elasticity, so it is widely used in many fields, such as synthetic leather, coatings, adhesives, sealants, and foams. Classification […]
Enhancing Sustainability: The Role of Anti-Hydrolysis Agents in PU Leather Production
With the increasing awareness of environmental protection and people’s pursuit of sustainable products, PU leather is becoming increasingly popular in the market as an environmentally friendly product. What is PU leather? PU (Polyurethane) leather is a synthetic leather with a structure and production process that make it look and feel similar to genuine leather, but […]
