Food Grade LSR Baby Refrigeration Teether

# Food Grade LSR Baby Refrigeration Teether

---

Product Overview

The Food Grade LSR Baby Refrigeration Teether from 橡楚（湖北）橡胶有限公司 is a purpose-built infant soothing product manufactured from 100% food-grade liquid silicone rubber (LSR), designed to provide safe, effective relief for teething infants aged 3 months and above. Unlike traditional solid rubber or plastic teethers, our refrigeration-specific LSR teether retains gentle cooling properties when chilled in a refrigerator, delivering long-lasting, soothing comfort to inflamed, sore gums without becoming overly hard or brittle at low temperatures.

All our LSR baby teethers are produced in our controlled manufacturing facility located at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, with raw material sourcing and production processes aligned to international food contact safety standards. This product is fully moldable to custom shape requirements, with consistent material performance that supports repeated sanitization and refrigeration cycles without degradation, discoloration, or leaching of harmful substances. Our core selling points focus on uncompromised food safety, long-lasting cooling performance, and durable, baby-friendly design.

Technical Specifications

Material Properties

This teether is manufactured from addition-cure food-grade liquid silicone rubber, with the following core material properties:

Physical Performance

Finished teether products are tested to the following physical performance standards:

Process Parameters

For custom manufactured teethers aligned to client design requirements, our standard production parameters are:

• Molding process: Compression injection LSR molding
• Curing temperature: 150–160°C
• Curing time: 60–90 seconds per part
• Secondary post-curing: 4 hours at 120°C to eliminate residual volatile organic compounds (VOCs)
• Surface finish: Matte non-slip finish (standard) or gloss finish (available on request)

Product Advantages

1. Optimized Cooling Performance for Refrigeration Use

Unlike lower-grade silicone or alternative polymer materials, our LSR formulation is specifically engineered for repeated refrigeration. When chilled at 0–4°C (the standard temperature of a refrigerator compartment), the teether retains a gentle, flexible texture that will not harden to the point of damaging infant gums or causing discomfort. The dense, uniform LSR material holds cooling energy consistently, providing 20–30 minutes of continuous soothing relief, which is 30% longer than ordinary silicone teethers in side-by-side testing. It is not designed for use in freezers, and will not crack or become brittle if accidentally frozen short-term.

2. Uncompromised Food Safety for Infant Use

We source only virgin food-grade LSR raw materials, with no recycled silicone or filler additives added during production. Every batch of material and finished product is tested for heavy metal content, residual volatile compounds, and harmful additives, meeting the strictest international food contact safety requirements for infant products. The non-porous surface of LSR prevents bacteria, mold, or food residue from becoming trapped in the material, reducing the risk of oral infection for teething infants.

3. Excellent Durability and Sanitization Compatibility

Our LSR teethers support all common infant product sanitization methods, including boiling (up to 10 minutes), steam sterilization, dishwasher cleaning, and disinfection with food-grade sanitizing wipes. The material will not degrade, discolor, or lose mechanical properties after 500+ cycles of sanitization and refrigeration, resulting in a usable life that matches or exceeds the teething stage of most infants. It also resists puncture and tearing from infant gums and emerging teeth, with no small parts that can break off and create a choking hazard.

4. Customizable Design Capabilities

As a professional LSR manufacturer, we support full customization of teether shape, size, hardness, and color to match your brand and product requirements. We can add texture patterns for additional gum stimulation, integrated handles for small infant hands to grip, and brand marking via embossing or pad printing, with no compromise to material safety or performance.

Applications

This Food Grade LSR Baby Refrigeration Teether is designed for the following core use cases and industries:

1. Retail Infant Care Products: As a standalone soothing product for sale through baby product retailers, e-commerce platforms, and pharmacy chains, marketed to parents of teething infants aged 3–12 months.
2. Baby Gift Sets: Integrated into newborn gift bundles and welcome kits for new parents, paired with other infant care accessories.
3. Hospital and Maternity Clinic Distribution: Provided as a complimentary educational or welcome product for new families leaving maternity care facilities.
4. Private Label Infant Brands: Manufactured under private label agreement for regional and international infant product brands looking for a high-quality, safe cooling teether offering.

Usage Notes:

• Always inspect the teether for damage, tears, or wear before each use. Discard immediately if any damage is detected.
• Chill only in the refrigerator (0–4°C). Do not freeze, as excessive cooling may increase hardness and cause discomfort.
• Always supervise infants during teether use to prevent choking hazards.
• Clean and sanitize the teether before first use and after each use to maintain hygiene.

Selection Guide

Hardness Selection

We offer three standard Shore A hardness options to match different teething stages:

• 30 Shore A: Extra soft, ideal for early teething (3–6 months) when gums are most sensitive and first teeth are beginning to emerge.
• 35 Shore A: Medium soft, the most popular all-stage option, suitable for 3–12 months through all teething phases, balancing flexibility and gentle resistance for gum stimulation.
• 40 Shore A: Firm soft, ideal for late teething (8–12 months) when multiple teeth have emerged and infants prefer more resistance for chewing.

Size Specifications

We maintain standard tooling for common teether sizes, and can develop custom tooling for unique shapes per client order:

• Standard small teether: 70mm × 50mm × 10mm, suitable for small infant hands
• Standard large teether: 90mm × 60mm × 12mm, with integrated handle for easier gripping
• Custom sizes: Tolerance of ±0.2mm for custom dimensions per client CAD drawings

Material Grade

All our refrigeration teethers use the same food-grade LSR formulation, aligned to FDA and EU food contact standards. We only offer one material grade for this product to ensure consistent safety, no lower-cost non-food grade alternatives are used for this product line.

Quality Assurance

At 橡楚（湖北）橡胶有限公司, we maintain a full quality management system certified to ISO 9001, with strict quality control checks at every stage of production:

1. Incoming raw material inspection: Every batch of LSR is tested for material conformity and safety before entering production.
2. In-process inspection: Dimensional and visual checks are conducted every 2 hours during production to ensure consistency.
3. Finished product inspection: 100% visual inspection for defects, plus random batch testing for physical performance and food safety compliance.
4. All custom orders are provided with a batch test report upon request.

Our production facility is located at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, where we follow strict clean production protocols to eliminate cross-contamination between non-food grade and food grade LSR products.
