To start a sponge foam factory, what mechanical equipment do you need to understand? Let me briefly introduce the required machinery.
Foam products are subject to high consumer demands for comfort and performance. Therefore, manufacturers must rely on advanced testing tools to ensure the quality and consistency of their products. Here are some devices used for foam product testing fyr.
Yellowing in polyurethane foam can be attributed to various factors and falls into four main categories:
Polyurethane foam(PU foam) primarily consist of polyurethane as their main component. The raw materials primarily include polyisocyanates and polyols, with the addition of various additives, the most crucial of which are a series of foaming agents related to the foaming process.
The apparent hardness of polyurethane foam is predominantly shaped by the following elements:
In China, a foam density of around 50 is considered good, as anything over 50 likely contains additives that you might not want in your foam.
Within the industry, sponge foam is typically classified according to its density. In the market, you can commonly find two primary categories of sponge foam: high-density sponge foam and regular sponge foam. These two types are easily distinguishable by their appearance and texture.
Polyurethane synthesis and its associated materials generally employ two main categories of catalysts: tertiary amine catalysts and organometallic catalysts.
There are many different types of polyurethane flexible foams on the market, following are a few popular varieties types for your reference:
Numerous aspects need to be taken into account when selecting high-quality latex foam. Here are some recommendations to assist you in choosing premium latex foam:
