3D printing breathable release film, UV curing oxygen permeable release film
Application: 3D printing, UV light curing, electron beam (EB) curing, release film, non-stick easy-to-peel film,
Working scene: attached to the bottom of the resin tank, one side is in direct contact with the photosensitive resin emulsion, and the other side faces the light source.
Performance: (VS similar competing products in the market)
1. High light transmittance:
UV light can pass through quickly and efficiently. Reflection, refraction, and diffraction effects are low, and the impact is small.
Single-layer structure, non-multi-layer composite, fewer interfaces passed by light, fewer refractions, high overlap between the light spot and the target irradiation area, and small offset.
Single component homogeneity, the same refractive index, less light scattering, high light concentration, and small irradiation offset error.
Based on the reasonable structure at the microscopic level, such as crystallinity, chip shape and arrangement, molecular chain structure and arrangement, surface roughness, etc., improve the transmittance of effective light.
2. UV stability:
The film can withstand long-term UV exposure, is not easy to age, turn yellow, become brittle, and has low photosensitivity.
Non-fluorine material, environmentally friendly, low photosensitivity, long life, and low average cost of use.
3. Low mechanical deformation:
The film bears the gravity of the resin, the pressure of the printing platform and the pressure of the resin curing on the film.
Based on the mechanical analysis of the peeling process, select the material and model with suitable molecular weight and physical properties, and control the production and ensure the mechanical properties of the film.
4. Chemical stability：
Resistance to solvent swelling and dissolution.
Based on the testing and evaluation of different emulsion systems and components, select the film material with the best chemical compatibility.
5. Anti-pollution:
The emulsion has little adhesion and residue, and can be cleaned and restored.
Based on different emulsion systems and components, test and select the film material with the most suitable surface energy.
6. Low adhesion:
The resin is easily separated from the film surface after curing, without residue, and the printing efficiency and yield rate are high.
Based on the observation and analysis of the separation interface and separation process under microscopic conditions, the relevant specific properties are enhanced and improved, including contact area and air permeability, so as to achieve slow attenuation of low peeling properties and long service life under multiple separation conditions.
