Silicone applications in nuclear power plant installation: Future trends and new markets
Driving Sustainability Forward: The Role of Silicone Elastomers
The global warming potential and environmental regulations pose challenges to shareholders involved in chemical production, part and component manufacturing, and original equipment manufacturers (OEMs).
  • New solutions can help reducing energy input, waste, and emissions along the supply chain. Recent advancements in chemical processes have enabled the production of silicone elastomers with significantly lower volatile content and reduced presence of siloxanes.
  • New formulations and optimized curing technologies support a liquid silicone rubber (LSR) injection molding process that offers shorter cycle times and lower molding temperatures leading to reduced energy costs and a lower CO2 footprint in part manufacturing
  • New products enable the adoption of advanced technologies for New Energy Vehicles.

Biomedical & Implant-grade Silicone Elastomers : Regulatory Considerations and a Case study
Silicone elastomers have long been used in medical and biomedical applications due to their chemical inertness, biocompatibility, and mechanical properties. Within this field, long-term implants (defined as medical devices staying 30 days or more in the body) represent the most demanding application. Regulations applying to this class of medical device have an impact on the expectations of medical device manufacturers to their silicone supplier. After reviewing a few of these expectations, we will focus on a case study about drug-eluting devices; adding on top the challenges of the chemical compatibility between the drug and the silicone network.

Session 3: 2K PARTS IN LSR
Customer-oriented evaluation strategy: from customer wishes to successful Value Evaluation Management for parts made of LSR or 2-Shot
2k Parts In LSR: New Approaches
We will be discussing the production of 2K (two-shot) parts, wherein at least one component is made of silicone. We will delve into the challenges involved in molding silicone and achieving robust adhesion with engineering thermoplastics. One significant challenge stems from the low viscosity of silicone. Our talk will explore a game-changing alternative that involves using molds with movable cores (core-back) and two channels, allowing for the sequential flow of different materials. This innovative system creates "compact" molds, offering a cost-effective solution that eliminates the need for expensive equipment like rotational plates or robot handling. By adopting these new concepts, we can transform consumer goods by producing parts with both soft-touch surfaces and rigid regions, while also exploring the use of different substrates in 2K parts with silicone, ultimately saving time and money.

Challenges With New Material Approvals in Aerospace
The presentation includes a journey through Honeywell Aerospace Yeovil exciting history of pilots’ oxygen systems development. Starting from equipping the first flight over Mount Everest, and developing high altitude flight systems through the century to achieve bespoke quality for highly technical jet pilots Environmental and oxygen systems working in high G. I will also explain the exciting science behind OBOG. The second part will explain the legacy rubber used by many aerospace companies. DTD specifications silicone rubber were withdrawn 30 years ago but still appear on many aerospace drawings. The third part will explain the process of reapprovals of new material and how time-consuming and high labour it can be.

Optimizing Addition Cure TIM
Thermal interface materials used in high performance electronics must satisfy multiple contradictory characteristics including high filler loading, while maintaining low viscosity for liquid dispensing and low hardness after cross-linking. Recent improvements in synthesis have made long chain silicon hydride available with terminal SiH hydride groups. By combining an SIH polymer and a divinyl polymer of equivalent molecular weights (MW) an overall lowering of the viscosity of the binder formulation can be achieved. This allows the final formulation to retain low hardness and high flexibility even when highly filled with thermally conductive materials. To minimize the viscosity a low MW, low viscosity vinyl polymer is used. To create long polymer chain lengths necessary for low hardness, a dihydride chain extender is selected. The closer to a 1:1 ratio between hydride and vinyl the less sensitive the formulation. Use of a SiH chain extender of equivalent MW to the vinyl polymer can minimize property variation due to weigh-up deviation.

Understand and Predict Shrinkage of Silicones
Simulation of LSR production processes is already state of the art. A lot of companies are using SIGMASOFT® Virtual Molding to predict the mold temperature as well as filling and curing during the process to avoid problems in production and optimize the cycle time. Nevertheless the prediction of process shrinkage often leads to issues since necessary material data are not available and characterization procedures are not yet established. Together with several partners SIGMA Engineering GmbH is working on new procedures to predict the process dependent shrinkage of LSRs. In the presentation first results as well as the cooperation with partners and material suppliers will be discussed.

Review of relevant standards for post-curing ovens
In the presentation we will share ageing test results that have been performed based on the BfR determination. Delegates will also hear about the newly issued ISO 188:2023 and the relevant apparatus. Finally, a process proposal based on the EN 1539 would allow for energy savings and allow for discussion.

Crosslinking Peroxides for Silicone Elastomers
Peroxide crosslinking of high temperature vulcanization (HTV) silicone rubber compounds can be carried out with a variety of organic peroxides. As the product range of organic peroxides and silicone rubbers is broad, it does lead to a multitude of possibilities to fulfill process and final market requirements. Unfortunately, the wide choice of products does also lead to some confusion due to poor understanding of the curative. To facilitate selection of the correct organic peroxide, details of general purpose and vinyl specific peroxides will be highlighted. Characteristics of the most important organic peroxides used to produce silicone rubber articles, will be highlighted; special attention will be given to a halogen-free general purpose peroxide. With this presentation the chemistry behind the cure process is explained in more detail. The importance of vinyl-units, playing an important role in the “addition cure process” of silicone rubbers, will also be shown and commented upon.
