Question 1

Can graphene composite plastic really replace aluminum heat sinks?

Accepted Answer

Yes, in many applications. Doolike graphene composites deliver sufficient thermal conductivity for most consumer electronics, LED lighting, automotive modules and battery cases — while offering 50–60% weight reduction, corrosion immunity, design freedom for complex one-shot shapes, and lower tooling-to-part cost at volume. For ultra-high heat flux applications (CPU, power electronics >100 W/cm²), copper/aluminum still wins — but the range suitable for graphene composites is large and growing.

Question 2

What thermal conductivity can Doolike graphene composites achieve?

Accepted Answer

Depending on base resin and graphene loading, our thermal conductivity typically ranges from 2 to 20 W/m·K — roughly 10–100× neat plastic (~0.2 W/m·K). We offer tiered formulations so you can balance conductivity, mechanical strength and cost. Share your target heat flux and ambient conditions — we will recommend the right grade.

Question 3

Why has graphene composite plastic only become practical recently?

Accepted Answer

Two industry-wide technical pain points historically limited performance: (1) uneven graphene dispersion in polymer matrix creates localized defects; (2) weak interfacial bonding between graphene and polymer prevents efficient heat transfer. The Doolike process solves both through surface modification and specialized compounding — enabling reliable, repeatable thermal performance.

Question 4

What types of parts are best suited for graphene thermal composite plastic?

Accepted Answer

Best-fit applications include: consumer electronics heat sinks (power banks, phone chargers), photography/cinema equipment cooling, automotive control module housings, outdoor LED lamp fins and housings, EV battery case dissipation, and any part where complex shape or weight matters more than absolute peak thermal conductivity. Injection-molded geometry enables integrated fins, mounting bosses and connector cutouts in a single shot.

Question 5

Are graphene composites safe for consumer and automotive products?

Accepted Answer

Yes. Doolike graphene composites use non-friable, fully encapsulated graphene bonded in polymer matrix — no loose particles released during normal use. Compounds comply with RoHS, REACH and relevant consumer safety standards. Full material declarations and compliance reports available upon request.

Question 6

What is the MOQ and lead time for graphene composite plastic?

Accepted Answer

Sample MOQ starts at 5 kg for evaluation grades. Production MOQ typically 200 kg for standard formulations. Lead time: 1–2 weeks for standard grades from stock, 4–6 weeks for custom formulations. Combined mold + molding service adds 6–10 weeks for full part validation.
