Purchasing Guide

Based on real user feedback, we provide the following suggestions:

For procurement needs that require the use of graphite polystyrene boards, it is recommended to prioritize confirming key technical parameters such as thermal conductivity, compressive strength, and fire rating to ensure that they meet the insulation requirements of building exterior wall insulation or cold chain logistics scenarios.
When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support or platform statistical information. Such suppliers can usually provide more stable product supply and after-sales service.
In special scenarios such as industrial plants or low-temperature storage, attention should be paid to the density and dimensional stability of graphite polystyrene boards to avoid material deformation or performance degradation caused by environmental temperature differences.
When purchasing graphite polystyrene boards, it is usually necessary to focus on the supplier's industry performance and actual cases, especially in high-rise buildings or energy-saving renovation projects. Mature application experience can help reduce procurement risks.

Knowledge Base

Graphite polystyrene insulation and sound insulation board

This article analyzes the core advantages of graphite polystyrene insulation and sound insulation board in floor applications, including its unique honeycomb structure design, dual effect performance of sound and heat, and the key points to be noted in base treatment during construction, to help readers fully understand this innovative building material.

What are the advantages of using graphite polystyrene board in cold storage

The application of graphite polystyrene board in cold storage has significant advantages. From the perspective of insulation performance, it has a closed cell honeycomb structure, with a large number of independently closed cells resembling small insulation units, limiting air convection and conduction, and reducing heat loss.

What is graphite polystyrene board

Graphite polystyrene board: full name of graphite molded polystyrene foam (commonly known as "black foam" or "blackboard", referred to as SEPS), widely used in building internal and external wall insulation system; Combustion performance of graphite polystyrene board: reaching B1 level (flame retardant); Not only does it add the flame retardant used for ordinary polystyrene board fire prevention (which is prone to volatilization when exposed to high temperatures), but it also contains infrared reflectors mixed in the raw materials.
