RTV silicone rubbers used in biomedical applications

biomedical applications

Introduces the world’s Biomedical application mask that revolutionizes face mask’s quality and safety

Active electric field, moisture-driven power generation technology for PTFE filter

Not only PTFE filter technology giving a 99.9% protection, but we also employing a patented physiological electric field-induced antimicrobial impact, which help to kill virus and bacteria for up to seven days. The technology uses the metal powder matrix of the embedded micro battery to generate an electric field when the breath of moisture generates a conductive medium, harnessing the power of electricity to reduce the risk of infection. It can be eliminated within one minute after contact, resulting in damage to the structural integrity of the virus, and reduces the ability of the virus to infect.

Improved Safety and Wearability

The biocompatibility silicone is made of medical-grade silicone, which is biocompatible and has good anti-allergic properties. It uses special room-temperature-vulcanizing silicone material. Fluorine-containing elastomer, fluorine rubber, and fluorine-containing rubber are excellent sealing materials with compressibility. It is resistant to chemicals, oil, ozone, sunlight and extreme temperatures (minus 15 ~ 400°F); it is biocompatible and has good anti-allergic properties. It reduces allergies and “rubber” feelings. It does not cause skin allergies, easier to clean, and won’t wear off.

Nex-Si committed to researching and developing the world’s only new technology,

Our strategic partner, Nex-Si committed to researching and developing the world’s only new technology, the Ion technology successfully developed the new plasma surface treatments for RTV silicone and electroplating products. Used in biomedical materials applications, the plasma silicone surface treatment is as smooth as baby skin, greatly improved product quality. It separates us apart from the rest of common silicone products and/or rubber watchbands, which are generally processed with a layer of oil, making the watchband softer and more comfortable to the touch. Consequently, it brings out the allergic symptoms to wearers while our RTVmask won’t’ have to worry about.
RTVmask has excellent resistance to weather and disinfection. It passes SGS, ROHS, FDA, and additional biocompatibility (skin irritation, skin allergy, cytotoxicity) related food and medicine certification test standards. Its adjustable titanium binding bridge is designed ergonomically to ensure a perfect fit for all people. Note that respiratory protection can only be effective when the air smoothly passes through the filter device.

the world’s smallest, lightest, and most effective mask for protection against bacteria and viruses

iso-certified silicone that ensures an ergonomic fit and minimizes skin irritation.​​

the gel form of silicone is used in bandages and dressings, breast contact lenses, and a variety of other medical applications

new process technologies that optimize healthcare device quality and safety

Nexsi’s manufacturing facilities are ISO 13485 certified by the International Organization for Standards for medical-grade silicone devices. The company is also FDA registered for its breast implant devices.

As an added benefit, silicone is environmentally friendly compared to plastics. Over time, silicone breaks down into small particles that are harmless to the environment.

By creating a manufacturing environment that is the equivalent of outer space, Nex-si virtually eliminates air bubbles and creates a stable silicone mixture that ensures quality precision casting. This innovative manufacturing process is particularly important for healthcare devices that use multiple silicone substances, such as a mix of soft, gel, and hardened silicones, in the manufacture of a single device.

“Nexsi’s ground-breaking new approach to silicone manufacturing technology is the key to the RTV Respirator Mask’s snug yet comfortable fit..”

PRO PTFE membrane

99.8% against PM 0.075 Personal Protective Military Specifications

With 70nm membrane physical filtration, utilizing the nanoporous structure of the membrane, 99.9% of particulate matter larger than 0.075μm can be filtered. Furthermore, 95% of oil particles can be blocked. PTFE is also waterproof, air permeable, oil-resistant, and more, providing effectively perfect defense.

RTV mask Fit test & Fit check

Protection from airborne contaminants. Fit is critical – one size does NOT fit all

Face

Faces can vary widely in shape, size and proportion, so selecting the correct model is vital for safe fit

good seal

Faces can vary widely in shape, size, and proportion, so selecting the correct model is vital for the safe fit

Tight-fitting

Tight-fitting respirators should be tested: disposable respirators

Fit Testing

Fit Testing should happen during the initial selection of RPE, before being worn in a hazardous environment

Fit Test methods

The most common Fit Test methods are the Qualitative Taste Test and Quantitative Particle Counting Device.​

Pressure

When fit checking, wearers use negative and pressure techniques to judge the quality of fit
