Question 1

What is the difference between antistatic, ESD dissipative, conductive and structural conductive plastics?

Accepted Answer

These four classes differ by surface resistance: Antistatic (10⁶–10⁹ Ω) prevents static charge buildup; ESD Dissipative (10⁶–10⁹ Ω) offers controlled dissipation; Conductive (10³–10⁵ Ω) actively conducts electricity; Structural Conductive (<10³ Ω) provides integrated low-resistance conductivity. Selection depends on your application — e.g. semiconductor wafer handling typically needs 10⁶–10⁹ Ω, while EMI shielding needs 10³–10⁵ Ω.

Question 2

Why choose CNT (carbon nanotube) modified plastics over carbon black filled ones?

Accepted Answer

CNT modification offers three major advantages over traditional carbon black: (1) Much lower filler loading (1–3% CNT vs 15–25% carbon black) preserves base resin mechanical properties; (2) Clean, non-sloughing surface — critical for semiconductor and cleanroom applications; (3) More stable resistance value across temperature, humidity and time. The tradeoff is higher raw material cost, offset by better performance in high-purity environments.

Question 3

Can Doolike supply conductive PEEK for semiconductor wafer carriers?

Accepted Answer

Yes. PEEK CF5999 (structural conductive, 10³–10⁵ Ω) and PEEK CN5419 (CNT conductive) are specifically designed for semiconductor fixtures and wafer carriers. These grades combine high temp resistance (up to 260°C continuous), chemical resistance to common wet etchants, cleanroom-compatible low particle shedding and stable surface resistance.

Question 4

What is the typical lead time for conductive plastic samples?

Accepted Answer

Standard grade samples ship in 3–7 business days from our Guangzhou warehouse. Custom formulation samples take 3–5 weeks including compounding, test molding and resistance verification. We typically provide 1–3 kg sample with resistance test report and technical datasheet at no cost for qualifying inquiries.

Question 5

Are these conductive plastics moldable on standard injection molding machines?

Accepted Answer

Yes. All Doolike conductive/antistatic compounds are designed for standard injection molding processes. Some considerations: CNT-filled grades require slightly higher barrel temperatures (+10–20°C vs neat resin), and mold surface should be polished to Ra 0.4 or better to prevent fiber/CNT surface visibility. We provide processing guidelines with every order.

Question 6

Do you offer ESD-safe POM for gears and precision mechanical parts?

Accepted Answer

Yes. POM CN5411 (CNT antistatic, 10⁶–10⁹ Ω) and POM CF9764 (CF reinforced antistatic) combine excellent wear resistance, self-lubrication and dimensional stability with static dissipation — ideal for semiconductor sorter handling gears, precision bearings, instrument internals and automation slides.

Question 7

Can custom surface resistance targets be formulated?

Accepted Answer

Yes. Doolike R&D can develop custom formulations targeting specific resistance values (within thermodynamic feasibility — typically anywhere in 10¹–10¹² Ω range). Share your base resin, target resistance range, operating temperature and key mechanical requirements — we’ll propose a formulation with test data typically within 4–6 weeks.
