High-Quality Eco-Friendly LSR Products and Molding Challenges by JOKER Industrial

Overview of LSR Material and Its Applications

LSR (Liquid Silicone Rubber) has become an essential material in modern industries due to its outstanding physical properties and eco-friendly characteristics. LSR offers high transparency, excellent resistance to extreme temperatures, and superior chemical stability, making it a standout in various sectors.

From medical devices and automotive parts to electronics, LED lighting seals, and high-performance gaskets, LSR’s applications are incredibly diverse, particularly in high-demand scenarios.JOKER Industrial is committed to producing environmentally friendly LSR products, utilizing advanced LSR molding technology to meet diverse needs, ensuring efficient and sustainable production.

Material Characteristics and Advantages of LSR

Compared to common materials like TPE, NR, NBR, PU, and EPDM, LSR stands out for several key reasons:

• 1. Temperature Resistance: LSR remains stable within a wide temperature range of -40°C to 230°C, whereas TPE and PU may deform or degrade under these conditions. This makes LSR particularly suitable for applications requiring high reliability, such as medical devices and automotive components.
• 2. Chemical Stability: LSR boasts excellent resistance to acids, alkalis, and oils, surpassing the performance of natural rubber (NR) and nitrile rubber (NBR), making it ideal for environments involving chemical exposure.
• 3. Biocompatibility: LSR complies with stringent medical-grade standards, making it non-toxic and odorless, ideal for products that require long-term contact with the human body, such as medical catheters and baby pacifiers.
• 4. Transparency and Anti-Yellowing: LSR’s high transparency and UV resistance prevent yellowing over time, making it a perfect material for optical applications such as lenses and lighting fixtures.
• 5. Environmental Benefits: LSR (Liquid Silicone Rubber) surpasses EPDM, PU, and NBR in both environmental impact and durability. Made from silica, LSR has a lower carbon footprint and does not release volatile organic compounds (VOCs) or polycyclic aromatic hydrocarbons (PAHs) during use. Additionally, LSR does not produce nitrogen oxides (NOx) or sulfur dioxide (SO2) when burned, making it superior to EPDM in terms of material stability and environmental impact.

These advantages position LSR as the material of choice across various industries that demand high performance and environmental sustainability.

Versatile Applications Across Industries

Given its excellent material properties and eco-friendly characteristics, LSR is a new type of organic silica gel material that is non-toxic, tasteless, weatherproof, and chemically inert. This silica gel has low viscosity (fluidity before vulcanization), making it ideal for advanced applications.

• 1. Medical Silicone: LSR’s biocompatibility and non-toxic nature make it an ideal material for medical catheters intended for short-, medium-, and long-term implantation. Silicone material can withstand repeated sterilization conditions and maintains high physiological stability.
• 2. Automotive Cable Seals: LSR’s resistance to extreme temperatures and chemical stability are widely applied in the automotive industry to ensure reliable sealing and extend the lifespan of components.
• 3. LED Lenses and Seals: LSR’s high transparency and anti-yellowing properties provide long-term stable optical performance in LED lighting applications.
• 4. Concave and Convex Lenses: Utilizing LSR’s optical properties and heat resistance, lenses can be produced that do not yellow when exposed to heat, achieving precise light refraction and focusing effects.
• 5. O-Rings in Various Industries: LSR O-rings are widely used in automotive, medical equipment, and electronics for their superior resistance to extreme temperatures, chemicals, and elasticity, offering long-lasting sealing performance.
• 6. Electronic Seals: LSR’s electrical insulation and weather resistance make it an ideal sealing material in electronic devices. These seals protect internal components from moisture, dust, and other contaminants, extending the lifespan of electronic devices.

Challenges in LSR Molding Technology

Despite the many advantages of LSR, its molding process (LSR molding) presents several challenges. LSR’s low viscosity and high flowability allow it to penetrate every detail of the mold, which is beneficial for creating complex structures but also increases the difficulty of controlling the molding process. This is especially critical when producing high-precision medical devices and automotive components, where the design and precision of the mold are crucial. Additionally, LSR’s rapid curing process requires high temperatures and pressure, demanding precise control over temperature and timing, as even the smallest errors can lead to product defects.

Advantages of Wittmann Battenfeld Production Equipment

JOKER Industrial has chosen Wittmann Battenfeld, a global leader in production equipment, to overcome the technical challenges associated with LSR molding.

At JOKER Industrial, we utilize the Elmet rubber feeding machine to mix the AB agent and the Wittmann Battenfeld silicone gel machine to combine the two groups of AB agents. The mixture is then injected into the mold, followed by rapid vulcanization through injection molding.Wittmann Battenfeld’s LIM (Liquid Injection Molding) technology is specifically designed for liquid silicone rubber, allowing for precise control over every parameter in the injection molding process. This ensures even distribution and rapid curing of LSR, significantly reducing the risk of product defects while improving production efficiency.
