EPS Raw Material Selection Guide

EPS (Expanded Polystyrene) is a commonly used packaging and insulation material. When selecting EPS materials, it is important to consider factors such as product performance, quality, and price, as well as the actual application scenario and demand, and choose the appropriate EPS material grade. The table above shows the different grades of EPS materials, including P grade, F grade, black EPS, graphite EPS, and white EPS.

EPS Grade	Density Range (kg/m3)	Compressive Strength Range (kPa)	Thermal Conductivity Range (W/mK)	Examples of Applications
P Grade	10-25	70-250	0.032-0.040	Insulation board for building, packaging material, etc.
F Grade	20-40	150-400	0.030-0.040	Insulation board for building, cold storage panel, etc.
Black EPS	10-30	70-250	0.032-0.040	Packaging material, cushioning material, etc.
Graphite EPS	15-30	100-250	0.032-0.040	Insulation board for building, packaging material, etc.
White EPS	10-40	50-250	0.030-0.040	Insulation board for building, packaging material, etc.

 

When selecting EPS materials, the following aspects should be considered:

1. Application scenario and demand: Different application scenarios and demands have different requirements for the performance of EPS materials. The appropriate EPS material grade should be selected according to the actual demand.
2. Product performance: EPS material performance includes density, compressive strength, thermal conductivity, and other indicators. The appropriate product should be selected according to actual application requirements.
3. Product quality: The quality of EPS materials directly affects their service life and effect. It is necessary to choose products from reputable manufacturers and brands to ensure the quality and reliability of the product.
4. Price: The price of EPS materials varies depending on the brand, grade, and specifications. The appropriate product should be selected according to the actual budget. However, it is important to note that price is not the only consideration, and it is more important to choose the right product to meet actual needs.

When selecting EPS materials, the following issues should also be noted:

1. Environmental protection: The production of EPS materials generates a large amount of wastewater and exhaust gas, which may have an impact on the environment. Therefore, environmentally friendly products or measures should be chosen to reduce the impact on the environment.
2. Transport and storage: EPS materials are prone to deformation and damage, and protective measures should be taken during transport and storage to ensure that the product is intact.
In summary, when selecting EPS materials, multiple factors should be taken into consideration, including application scenarios and demands, product performance, product quality, price, environmental protection, and transport and storage. Only by comprehensively considering these factors can the most suitable EPS material be selected to meet actual needs.
 
If you choose EPS material as the filling material for the hard seat, you need to select the appropriate EPS material grade and thickness to ensure the comfort and durability of the hard seat. Depending on the different EPS material grades, the comfort and durability of the hard seat will also vary. Therefore, it is necessary to select the appropriate EPS material grade and thickness according to actual needs to ensure the quality and comfort of the hard seat.
