How to solve the problem of Insufficient Hardness in Foam Boards

How to solve the problem of Insufficient Hardness in Foam Boards

1. Problem Analysis In the production of foam boards, sometimes the hardness is not sufficient, which can affect the product's durability and performance. This issue can arise from the following reasons:

1. Low Melt Temperature
2. Impure Raw Materials
3. Insufficient Physical Blowing Agents

2. Solutions To address the above issues, we propose the following solutions:

1. Increase Melt Temperature The hardness of foam boards is closely related to the melt temperature. If the melt temperature is too low, the physical blowing agents may not work effectively, leading to insufficient hardness. Therefore, the melt temperature can be slightly increased, ensuring it does not exceed optimal levels, to improve the effectiveness of physical foaming.
2. Improve Raw Materials If the raw materials are impure, such as containing air or other contaminants, it can also lead to insufficient hardness in foam boards. The solution is to use high-quality raw materials and remove any impurities.
3. Increase the Amount of Physical Blowing Agents Physical blowing agents are a key factor in determining the hardness of foam boards. If there is an insufficient amount of blowing agents, the board's hardness will be inadequate. Therefore, increasing the amount of physical blowing agents can help improve the hardness of the foam boards.
