Buy & Import heat sink graphite carbon sheet electrode from Laimeisi Silicone Industry - Wholesale Supply

Laimeisi Silicone Industry supplies a heat sink graphite carbon sheet electrode made from synthetic pyrolytic flexible graphite, also described as artificial graphite sheet. The product is delivered in rolls of 300 mm width or 60 mm width, each roll 50 m long. Thickness ranges from 0.017 mm to 0.4 mm, and the sheet meets TSM standards 500, 1500 and 1500‑D. It is classified as industrial grade C with a carbon content of 98‑99 % and a density between 1.5 and 2.2 g/cm³.

Flexible graphite sheets of this type are valued for their ultra‑high in‑plane thermal conductivity, which the supplier lists as 1500‑1800 W/m·K, exceeding the typical industry range of 1000‑1500 W/m·K. The material tolerates temperatures from - 40 °C to 400 °C and carries a UL94 V0 flammability rating, matching common safety standards for electronic components. Typical industry thicknesses fall between 0.05 mm and 0.5 mm, and standard tensile strength values lie in the 5‑30 MPa band, whereas this product offers a broader 9‑40 MPa range. Certifications such as ISO 9001, SGS, CTI and RoHS confirm conformity to quality and environmental requirements.

Buyers in consumer electronics, LED lighting, battery pack and automotive thermal management sectors use this sheet to replace metal heat sinks because of its lightweight and conformable nature. The supplier states that packaging follows the customer's request and that the goods are ready for dispatch three days after payment. Importers should confirm Incoterms, payment method and any custom dimensions before placing an order.

Sourcing heat sink graphite carbon sheet electrode from Laimeisi Silicone Industry - China Import Guide

Before placing an order, verify that the sheet meets your thermal performance needs by checking the supplied thermal conductivity, thickness and density values against your design criteria. Request the ISO 9001, SGS, CTI and RoHS certificates, as well as the UL94 V0 test report, to ensure the material complies with safety and environmental standards. Confirm that the carbon content and grade match the specifications required for your application.

The supplier indicates that the goods are ready for dispatch three days after payment, but the exact Incoterms and payment terms are not stated in the listing. Importers should negotiate and confirm the preferred Incoterm (for example FOB Shenzhen or CIF Shanghai) and agree on secure payment methods such as T/T or LC. Clarify any additional lead‑time requirements for custom sizes before confirming the purchase.

Arrange for a pre‑shipment inspection to verify thickness, thermal conductivity and tensile strength, using calibrated measurement tools. Request a test report that documents compliance with the stated specifications and certifications. Maintaining proper documentation, including a material safety data sheet and a certificate of conformity, will help streamline customs clearance and downstream quality assurance.
