Black PEEK products

Core Features

  • Enhanced Wear Resistance: Black PEEK is typically formulated as “Bearing-Grade,” blended with carbon fiber, graphite, and PTFE to provide a significantly lower coefficient of friction than virgin PEEK.
  • Static Dissipation (ESD): Many black PEEK variants are carbon-filled, providing essential Electrostatic Discharge (ESD) protection for sensitive electronic components.
  • High Load-Bearing Stiffness: The addition of carbon fiber reinforcements increases the flexural modulus and tensile strength, allowing parts to withstand higher mechanical loads without deformation.
  • Thermal Stability: Maintains exceptional dimensional stability and mechanical integrity in continuous operating temperatures up to 250°C (482°F).
  • UV and Chemical Immunity: The black pigmentation often provides enhanced resistance to UV degradation while maintaining absolute immunity to aggressive industrial solvents, acids, and bases.

At Kriloha Ltd., we recognize that extreme mechanical environments demand more than just standard polymer performance. Our Black PEEK Products represent our engineered answer for “Extreme-Wear-Durability” and “Static-Safe-Precision”. As a premier provider of customized industrial solutions, Kriloha has developed a specialized manufacturing division dedicated to processing these advanced composite matrices into high-performance physical realities.

The engineering of our black PEEK program is founded on Matrix-Optimization and Friction-Reduction. Unlike virgin PEEK, our black formulations are specifically tailored for dynamic applications where surfaces are in constant contact. By utilizing state-of-the-art 5-axis CNC machining, we ensure that every component—from intricate ESD-safe connectors to heavy-duty bearing cylinders—features perfectly smooth surface finishes and exact dimensional tolerances. At Kriloha, we verify the structural integrity of every carbon-reinforced geometry, resulting in “Failure-Resistant” parts that excel where standard materials melt or seize.

Manufacturing these advanced composite components involves strict Dimensional, ESD, and Thermal Verification. We collaborate directly with your engineering teams to determine the precise level of carbon or graphite loading required for your specific load, speed, and conductivity benchmarks. Whether you are prototyping a single high-stiffness bracket for an aerospace payload or scaling up production for a line of self-lubricating industrial rollers, Kriloha provides the exact material performance your facility demands. By choosing Kriloha Ltd., you are investing in a “Future-Proof” manufacturing partnership that masters the science of high-friction, high-heat environments.

Primary Use Cases

  • Dynamic Bearing & Bushings: High-speed rotating cylinders, sleeves, and rollers where self-lubrication and low wear are critical for long-term reliability.
  • Semiconductor Handling: ESD-safe wafer carriers, vacuum chucks, and guide rails that prevent static buildup and metallic contamination.
  • Aerospace Structural Parts: Lightweight, high-stiffness brackets and fasteners designed to replace metal components in high-vibration avionic environments.
  • Automotive & Racing Components: High-temperature engine sensors, thrust washers, and specialized gear components exposed to hot oils and friction.
  • Subsea Exploration: Corrosion-resistant housings and connectors for underwater robotics that require high compressive strength and chemical isolation.

Frequently Asked Questions

  1. What makes PEEK black?

The black color is usually the result of additives like carbon fiber, graphite, or carbon black. These are not just pigments; they are functional reinforcements that improve the material’s stiffness, wear resistance, or electrical conductivity (ESD properties).

  1. Is Black PEEK stronger than Natural (Virgin) PEEK?

Generally, yes. Carbon-filled black PEEK has significantly higher tensile strength and stiffness compared to virgin PEEK. This makes it ideal for structural components that must support heavy loads at high temperatures without “creeping” or deforming.

  1. Is Black PEEK safe for clean-room use?

Absolutely. Despite the additives, black PEEK remains a very low-outgassing material and generates minimal particulates. Its ESD properties actually make it a preferred choice in semiconductor clean-rooms to prevent static-attracted dust from contaminating wafers.

  1. Can Kriloha achieve the same tight tolerances with Black PEEK as with Natural PEEK?

Yes. While carbon-filled materials can be more abrasive on machining tools, our advanced CNC centers at Kriloha are optimized for processing reinforced composites. We maintain sub-millimeter precision regardless of the material matrix.

  1. Does Black PEEK require external lubrication?

In most cases, no. Because black PEEK often includes graphite or PTFE (bearing-grade), it is inherently self-lubricating. This is a massive advantage in industries like food processing or vacuum technology where liquid oils and greases are prohibited.
