Applications of two‑component liquid silicone rubber in the infant and children’s products sector are expanding.
2026-05-14 15:14
Recently, we have received feedback from customers in the compression molding and injection molding sectors, among whom… Silicone products for infants and toddlers (pacifiers, teething rings, feeding utensils, etc.) Enterprise demand is the most concentrated.
Unlike the precision manufacturing sector, these customers’ primary concerns center on three key factors: Quality degradation due to prolonged baking, discrepancies between domestic and international test results, and a comprehensive assessment of manufacturing costs.
In response to this, Betely conducted targeted validation and formulation fine-tuning for the disulfide-free system. , and currently possesses mature application capabilities in the infant and child products domain.
I. Core Value of the Two-Sulfur-Free Process: Eliminates the baking step and addresses multiple pain points.
After molding, traditional liquid silicone rubber requires a secondary vulcanization process that can take 4 to 8 hours or even longer, posing significant challenges for infant‑product manufacturing: high energy consumption, with electricity costs accounting for a substantial share of production expenses; difficult quality control, as oven contaminants readily adhere and transparent parts are prone to uneven yellowing; and low efficiency, due to lengthy curing cycles that delay delivery and tie up inventory.
The core advantage of the sulfur-free formulation: it achieves performance requirements in a single step, eliminating the need for a second baking process and completely addressing the aforementioned pain points.
II. Consistent testing standards to prevent result discrepancies at the source.
The domestic and international testing standards for infant and child silicone products are essentially the same. The reason behind customer feedback that “a product passes domestic testing but fails overseas” lies primarily in… Accuracy of testing equipment, weighing error in sampling, and pretreatment methods The differences. If ordinary liquid adhesives are not fully re‑vulcanized, they are prone to exceeding the permissible limits for low‑molecular‑weight residues when subjected to more stringent testing conditions.
The Betely free‑dibenzothiazole system controls low‑molecular‑weight content at the formulation stage; measured volatile content is ≤0.25%, eliminating the need for bake‑out rework. , in The results show good consistency under different testing conditions. , effectively reducing compliance risks.
III. Overall Cost: More Competitive Than Conventional Liquid Adhesives
Some companies initially opted for it due to the low unit price of ordinary liquid glue, but when factored in… Oven electricity costs, equipment depreciation, and labor and facility expenses , and Losses due to scrap and rework caused by poor baking and failed inspections Subsequently, the overall costs were relatively high.
Although the Betely–Miao disulfide‑free process may not have the lowest raw‑material costs, it… Overall manufacturing costs are lower, and the production pace is more controllable. 。
IV. Customization Capabilities: Flexible Adaptation to Address Real-World Process Challenges
Molds, molding processes, and product wall thicknesses vary significantly among different customers, often leading to issues such as difficult demolding, trapped air, and mismatched vulcanization cycle times. Betely sulfur-free system can be customized to meet specific requirements: Adjustable vulcanization time and temperature, optimized demolding performance, and a mold‑specific fine‑tuning formulation to address air entrapment.
Compared to some International brands have long formulation stabilization and adjustment cycles. the issue, Betely responds more flexibly and adjusts more efficiently.
V. Applicable Product Types
Currently, the infant and child‑related applications that have completed validation and are in stable supply include:
Material hardness can be selected within the range of 20–70 Shore A, and its mechanical properties meet the requirements for entry-level products.
The concept of “dual‑sulfur‑free” is not new, but its systematic application to silicone products for infants and young children is truly… Addressing baking yellowing, detecting variations, and performing cost accounting. Key issues require coordinated validation of both formulation and process.
Betely has a mature product portfolio and robust customization capabilities. Customers with specific needs are welcome to contact our technical sales team for sample testing or process evaluation.
