Due to its excellent performance, silicone rubber is used in various aspects. If you want to know the wholesale price of silicone rubber to determine if it is your best choice, you have come to the right place. In this article, we will introduce the silicone rubber cost to you.
What Affects Silicone Rubber Cost?
Before you know how much silicone rubber costs, you need to briefly understand the factors that influence silicone rubber cost. Here are four main influencing factors
Silicone Rubber Grade
Silicone rubber grade will affect the silicone rubber cost. Each silicone grade has different production standards and testing requirements, so its costs are different.
- Industrial silicone rubber: The manufacturing of industrial-grade silicone is the simplest, so the cost of industrial-grade silicone rubber is the lowest.
- Food-grade silicone rubber: Food-grade silicone needs to be odorless and non-toxic, and must have FDA or LFGB certification, so the food-grade silicone rubber price is higher.
- Medical-grade silicone rubber: Medical-grade silicone has the highest price because it needs to meet the highest medical-grade standards.
You need to choose the most suitable silicone rubber grade based on your industry and the type of silicone product.
Silicone Rubber Type & Manufacturing Process
Different types of silicone rubber also influence your silicone rubber price.
- Solid silicone rubber: Solid silicone is generally made by cutting it into pieces and placing them in a mold. It only requires a simple molding process, so solid silicone costs the least.
- HTV silicone rubber: High temperature vulcanized (HTV) silicone requires placing the silicone in a mold and vulcanizing it under high temperature and high pressure. The production process of this silicone is more complex, so the HTV silicone price is higher.
- liquid silicone rubber: The manufacturing process of liquid silicone rubber(LSR) is the most complex. It requires mixing different liquid components in a specific ratio. And it also needs to go through the liquid silicone injection molding process. Therefore, the LSR cost is the highest.
When purchasing silicone rubber, you need to select the appropriate silicone type based on your product features and applications.
Product Design Complexity
In addition, the product design complexity also affects the silicone rubber cost.
- Complex structure: The more complex the structure of your silicone product is, the more difficult its production will be. As a result, you need to pay more for silicone molding costs and silicone manufacturing costs.
