Purchasing Guide

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

  • For procurement needs that require the use of graphite polystyrene board, it is recommended to prioritize the confirmation of key technical parameters such as thermal conductivity, compressive strength, and fire rating to ensure compliance with performance requirements for building exterior wall insulation or cold chain storage 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 the fields of industrial plants and civil buildings, the thickness specifications of graphite polystyrene board (such as 50mm-120mm) need to be selected according to actual insulation needs, and different density models are suitable for load-bearing or non load-bearing structures.
  • When purchasing graphite polystyrene board, the evaluation can be based on the supplier's case performance in similar projects, with a focus on the product's applicability in segmented scenarios such as low-temperature cold storage or high-rise building fire isolation belts.

Knowledge Base

Q

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.

Q

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.
