Choosing the Right DLP Material: FR VO Black vs. PB10

For engineers working on projects with demanding material requirements, selecting the right resin can make a significant difference in performance, durability, and functionality. Matrix FR VO Black and Matrix PB10 are two advanced DLP materials that offer unique benefits, particularly in terms of flame retardancy, durability, and mechanical flexibility. Here’s a closer look at both materials and guidance on choosing the best fit for your application.

Matrix FR VO Black: High Performance with Flexibility

Matrix FR VO Black stands out for its flame-retardant properties, toughness, and ability to endure significant mechanical stress, making it an excellent choice for applications that require durability under impact or frequent handling. Key attributes include:

Enhanced Flexibility

With an impressive elongation at break of 44.6%, FR VO Black is well-suited to parts requiring flexibility. This level of elongation makes it ideal for clip features and other components that experience bending, twisting, or snap-fits.

Impact and Drop Resistance

The material’s resilience in drop tests and general toughness ensure that components retain their structure even after repeated impacts, making it a preferred choice for parts that undergo frequent handling.

Superior Flame Retardancy

Certified to UL94 V0 at 3mm thickness, Matrix FR VO Black is self-extinguishing, making it appropriate for use in high-safety applications in aerospace, automotive, and electronics.

Versatile Applications

From aircraft connectors to consumer electronics housings, FR VO Black excels in applications that require both mechanical strength and strict adherence to safety standards.

In summary, Matrix FR VO Black provides robust mechanical properties combined with flexibility, which helps prevent brittleness under repeated stress. It’s recommended when impact resistance and compliance with high flame retardancy standards are key.

Matrix PB10: High Rigidity with Excellent Environmental Stability

Matrix PB10 offers a different set of advantages. With a rigid structure and high-temperature resistance, PB10 is ideal for parts that require strength, environmental durability, and stability. Here are its defining features:

Thermoplastic-Like Rigidity

With a tensile strength of 63 MPa and elongation at break of 12%, PB10 delivers excellent rigidity, which is advantageous for components that must maintain dimensional stability under load. This rigidity makes it suitable for applications like motor housings and structural connectors.

Environmental Stability

Engineered for long-term use, PB10 resists environmental degradation, including UV exposure and humidity, making it ideal for outdoor and exposed environments.

Efficient Production

PB10 is designed for rapid production, with no need for secondary thermal curing. This, combined with its low-distortion characteristics, makes it a go-to material for achieving quick turnaround on high-quality parts.

Biocompatibility

Meeting ISO 10993 standards, PB10 can be used in applications where skin contact is a consideration, such as certain medical or wearable components.

In summary, while PB10 provides superior rigidity, its 12% elongation at break makes it more brittle than FR VO Black, which limits its use in applications requiring flexibility or impact resistance.

Summary: Choosing the Right Material for Your Project

Choose Matrix FR VO Black for applications needing flexibility, flame retardancy, and durability under repeated impact, such as clip mechanisms, snap-fits, and aerospace connectors.

Choose Matrix PB10 when your project requires high rigidity, heat resistance, and long-term stability in a stable environment, especially for parts like housings, connectors, and parts exposed to UV or chemical exposure.
