Insights into the function of raw materials in polyurethane foam formation

Polyols and isocyanates are the ubiquitous feed stocks for polyurethane foam. Polyols are a category of chemicals that help render the foam flexible. Isocyanates are a family of chemicals that sandwich with a compound called a polyol to make foam. Different families of polyols or isocyanates mixed in can alter the way the foam feels and functions. The foam could be made softer, for example, by using more of one rigid polyurethane. It’s like when you bake a cookie, the ingredients you put in can affect how the cookies taste and feel. 

The influence of the chemical structure on the properties of polyurethane foams

The chemicals used in polyurethane foam will determine whether the foam is hard or soft, dense or lightweight, and how well it can withstand heat or cold. If a foam has to support a lot of weight, as in a car seat, it must be constructed with certain chemicals to create enough stiffness. At SANYING, we select the chemicals we use to make sure we provide the required products of our customers whether they are after dense polyurethane foam for furniture, car, or thermal insulation. 

Optimal performance of products by appropriate choice of raw material

If you are picking the right stuff to make the polyurethane foam, is just like the selecting the right parts for the car. You use good parts and the car will perform better and last longer. We only choose high-quality material which is standard and beyond the standard! That way, the foam doesn’t just do good work, but it also lasts longer than other foams. 

Investigating the relationship between feedstock and PU foam service life

The service life of polyurethane foam is primarily determined by its chemical structure. All the foam can resist wear and tear, and hold up under pressure, if the right chemicals give it structure. This is particularly important for products like mattresses, where the foam must retain its feel and support for many years. At SANYING, durability is such an important commodity when we choose the material for our foam products. 

Maximizing foam characteristics with emphasis on chemical and property relations

For one to obtain optimal polyurethane foam, knowledge of each chemical impact on the performance and quality of the foam is necessary. At SANYING, we test different formulations to obtain rigid foam polyurethane with the best performance. It is through this process that we are able to engineer quality foam to suit certain needs, whether it be cushioning, insulation or support. That extra attention to detail means our foam products are second-to-none, and won’t let you down, no matter how it’s used.
