Liquid Silicone Rubber (LSR) overmolding is a specialized manufacturing process that involves the application of liquid silicone rubber onto a substrate or an existing component to create a protective or functional outer layer. This process is used in various industries, including automotive, medical, electronics, and consumer goods, to enhance product performance and durability. While LSR overmolding offers many advantages, such as excellent heat resistance, flexibility, and biocompatibility, there are common issues that manufacturers may encounter during the overmolding process. This article delves into the details of LSR overmolding and explores some of the common issues and their solutions.

Understanding LSR Overmolding

LSR is a high-purity, platinum-cured silicone rubber that is known for its exceptional properties, making it a preferred material for overmolding applications. The overmolding process involves the following key steps:

  1. Surface Preparation: Proper preparation of the substrate or the existing component is crucial. It should be cleaned and, in some cases, primed to ensure good adhesion of the LSR.
  2. Mold Design: The mold used for LSR overmolding needs to be designed to accommodate the substrate and allow the LSR to be injected or dispensed onto it. The mold’s design should also prevent flash and promote the proper flow of LSR.
  3. Injection or Dispensing: Liquid silicone rubber is either injected into the mold or dispensed directly onto the substrate using specialized equipment. The choice of method depends on the specific requirements of the project.
  4. Curing: LSR overmolding typically involves curing the silicone rubber at elevated temperatures to accelerate vulcanization and hardening. The curing process may use either compression or injection molding techniques.
  5. Demolding: Once the LSR has cured and solidified, the molded part is removed from the mold, often requiring the separation of the substrate and the LSR.

Reasons for degumming of silicone products

Silicone injection molding projects

The degumming of silicone products can occur for various reasons, and it is essential to identify and address the underlying causes to prevent or resolve this issue. Some common reasons for the degumming of silicone products include:

  1. Contamination: Contamination of the silicone material during production or processing can lead to degumming. Contaminants, such as oils, dust, or particles, can interfere with the bonding of silicone and result in reduced adhesion.
  2. Poor Adhesive Quality: The choice of adhesive or bonding agent used in the silicone product manufacturing process can affect adhesion strength. Using an adhesive that is not suitable for silicone or using low-quality adhesives may result in degumming.
  3. Inadequate Surface Preparation: Proper surface preparation is crucial to ensure good adhesion of silicone. If the silicone surface is not adequately cleaned, treated, or primed before bonding, it can lead to poor adhesion and eventual degumming.
  4. Temperature Extremes: Exposure to extreme temperatures, whether high or low, can affect the adhesive properties of silicone. Silicone products may degum when exposed to temperature fluctuations outside their designed range.
  5. Humidity and Moisture: High humidity or moisture can weaken the adhesive bond of silicone products, causing degumming. It is especially relevant in applications where silicone products are exposed to wet or damp conditions.
  6. Chemical Exposure: Exposure to harsh chemicals or solvents can break down the adhesive bond between silicone and other materials, resulting in degumming.
  7. UV Radiation: Prolonged exposure to ultraviolet (UV) radiation can degrade silicone materials and affect the adhesive bond. This is particularly relevant in outdoor or sunlight-exposed applications.
  8. Mechanical Stress: Repeated mechanical stress, such as bending, stretching, or shearing, can cause the silicone to peel away from the substrate, leading to degumming.
  9. Aging and Wear: Over time, silicone materials can naturally age and degrade, which can affect the adhesive bond and result in degumming.
  10. Manufacturing Issues: Poor manufacturing practices, such as incorrect curing times, inadequate pressure during bonding, or uneven application of adhesive, can contribute to degumming.

Is Liquid Silicone rubber waterproof?

Yes, liquid silicone rubber (LSR) is waterproof and known for its excellent water resistance. LSR is a popular choice for applications where waterproofing and moisture resistance are essential. Here are a few reasons why LSR is considered waterproof:

  1. Hydrophobic Nature: LSR is naturally hydrophobic, which means it repels water and does not easily absorb or retain moisture. This property makes it inherently resistant to water and moisture.
  2. Sealing Capabilities: LSR is often used for creating seals and gaskets in various applications. It forms effective seals against the ingress of water and other liquids when properly designed and molded.
  3. Chemical Resistance: LSR is resistant to many chemicals, including water. It does not degrade or break down when exposed to moisture, making it a reliable choice for waterproof applications.
  4. Durability: LSR is durable and maintains its properties even when subjected to environmental conditions, including exposure to water, UV radiation, and temperature fluctuations.
  5. Medical and Consumer Products: LSR is commonly used in medical devices, baby products, and kitchenware where water resistance is crucial. For example, baby bottle nipples and pacifiers made from LSR are safe and waterproof.
  6. Electrical Insulation: LSR is used in electrical and electronic applications due to its excellent insulating properties. It is capable of protecting components from moisture and maintaining electrical integrity.

It’s important to note that while LSR is waterproof, the effectiveness of waterproofing depends on the design and quality of the final product. Proper sealing and design considerations are necessary to ensure that LSR-based products effectively keep out water and moisture. Additionally, the specific LSR formulation and curing process can also affect its water resistance, so it’s crucial to work with experienced manufacturers or molders to achieve the desired waterproofing properties in your LSR products.
