Custom Compounds and Tubing

From Material Selection to Prototyping, Evaluation, and Mass Production—Backed by Proven Expertise and Technology

As medical technology advances and minimally invasive treatments become more widespread, medical catheters are expected to deliver increasingly sophisticated performance and meet diverse specifications.
Leveraging over a decade of expertise in polymer compounding and extrusion technologies, we offer high-performance compound materials and custom tubing with excellent X-ray opacity, processability, and extrusion stability. Through our unique network for sourcing raw materials and equipment, we offer cost-effective solutions while maintaining quality on par with major domestic manufacturers in Japan. We provide end-to-end support from the design stage to mass production, flexibly accommodating short lead times and small lot sizes—needs that are often challenging for large manufacturers to meet. Please feel free to contact us for your catheter development needs.

Capable of Meeting Diverse Design Requirements

Meeting Diverse Design Needs with High-Precision Extrusion Technology

Drawing on years of experience in polymer modification and extrusion molding, we consistently deliver the dimensional precision, surface quality, and reproducibility required for medical tubing. Our catheter manufacturing technology supports a broad range of design requirements, including precision extrusion, co-extrusion, tapering, and small-diameter or thin-walled tubing. With a fully integrated in-house system covering everything from compounding to molding, we ensure rapid prototyping and stable product quality. We also accommodate complex specifications such as single- and multi-lumen structures.
■ Examples of supported specifications:
• Single-/Multi-lumen tubing
• Co-extrusion molding
• Taper processing
• Small-diameter/Thin-walled types, etc.

Providing Custom Solutions

Comprehensive Support from Early Development to Mass Production

We provide technical expertise and experience to support the entire development process—from material selection to prototyping, evaluation, and the establishment of mass production systems. With a strong track record in customized solutions and joint development, we leverage our domestic and international networks to optimize the procurement of equipment and materials. Our goal is to deliver optimal solutions tailored to your needs—balancing cost, speed, and quality.

High-Quality Compound Materials

In-House Development of Highly Reliable Compound Materials

We offer a wide range of compound materials based on various resins such as TPU, PEBAX, and fluoropolymers. Our proprietary dispersion technology prevents the agglomeration of additives like barium sulfate, enabling uniform distribution and maintaining the mechanical properties of the materials while achieving high performance. These materials comply with RoHS/REACH regulations and are highly reliable. We also offer flexible customization for additive types and concentrations, as well as specific color requirements.We propose optimal material designs tailored to the application and design requirements of medical devices.
• Base resins: Fluoropolymers (FEP, ETFE, etc.), elastomers, others (PP, LDPE, PEEK, etc.)
• Additives: Radiopaque agents (barium sulfate, tungsten, etc.), colorants, reinforcing agents, and more
