Micronized oxidized polyethylene wax (MPOW) can serve various purposes in photopolymer formulations, which are commonly used in stereolithography (SLA) and digital light processing (DLP) 3D printing technologies, as well as in other applications like coatings, adhesives, and dental materials. Here are some potential uses of MPOW in photopolymer formulations:

Surface Properties

MPOW can be added to photopolymer formulations to modify surface properties such as gloss, smoothness, and abrasion resistance. It can enhance the overall appearance and tactile feel of printed objects.

Anti-blocking Agent

In photopolymer formulations, MPOW can act as an anti-blocking agent, preventing the sticking of cured layers to the printing surface or to each other during printing and post-processing.

Flow Control

By adjusting the particle size and concentration of MPOW in the formulation, it can help control the flow characteristics of the photopolymer resin. This can improve printability and reduce issues like resin dripping or oozing during printing.

Thixotropic Properties

MPOW can impart thixotropic properties to the photopolymer formulation, meaning it becomes less viscous under shear stress (such as during mixing or printing) and returns to its original viscosity when the stress is removed. This property can aid in the printing process by improving resin flow and preventing settling of particles.

Improved Mechanical Properties

Incorporating MPOW into photopolymer formulations can sometimes enhance mechanical properties such as toughness, impact resistance, and elongation at break. This is particularly useful in applications where printed parts require high durability.

Post-Processing Ease

MPOW can facilitate easier post-processing of printed objects by reducing adhesion to supports or build platforms, allowing for easier removal and cleaning of printed parts.

UV Stability

MPOW can contribute to the UV stability of photopolymer formulations, helping to prevent degradation of printed parts over time when exposed to UV light. Overall, MPOW offers a range of benefits in photopolymer formulations, from improving surface properties and printability to enhancing mechanical performance and post-processing ease, ultimately leading to better quality prin
