Food-grade LSR Pet Chew Rope Connector

As specialized LSR product manufacturers, we engineered this connector to solve common pain points of traditional pet toy connectors: rigid plastic connectors that crack after repeated chewing, rubber connectors that leach harmful substances, and porous materials that trap bacteria and food residue. Our LSR construction delivers a soft, non-abrasive surface that protects pets’ teeth and gums while maintaining structural integrity through thousands of chewing cycles. The component is designed to securely hold braided or twisted chew rope ends, preventing fraying and extending the service life of the entire pet chew toy.

All raw materials used in this product are sourced from qualified global silicone suppliers, with full traceability from material intake to finished product shipment. We maintain consistent manufacturing controls to ensure every connector meets uniform quality and dimensional standards, making it suitable for mass production integration into commercial pet toy lines.

Process Parameters

For our in-house molding production, we maintain the following controlled parameters to ensure consistent product quality:

• Injection temperature: 160℃ – 180℃
• Curing time: 60s – 120s (varies by connector thickness)
• Post-curing treatment: 4 hours at 120℃ to eliminate residual low-molecular-weight siloxanes
• Dimensional tolerance: ±0.1mm for core connection dimensions, meets custom matching requirements for standard chew rope diameters

Product Advantages

1. Food-grade safety, non-toxic and harmless

Our pet chew rope connector uses 100% food-grade LSR raw material, free of BPA, phthalates, lead and other harmful substances recognized in pet product safety regulations. The non-porous surface does not absorb saliva or food residue, preventing bacterial growth and making it safe for long-term contact with pets’ mouths. This compliance allows pet product brands to meet global retail safety requirements for pet toys.

1. Excellent chew resistance and long service life

Compared to thermoplastic rubber (TPR) and general-purpose solid silicone connectors, our LSR product offers superior tear strength and fatigue resistance. It withstands repeated biting, pulling and twisting from medium and large dogs without cracking, deforming or breaking apart. The soft elastic texture absorbs bite impact, reducing stress on pets’ teeth and jaw compared to rigid plastic alternatives.

1. Easy to clean and maintain

The non-stick LSR surface repels dirt and hair, and can be cleaned quickly with mild soap and water, or disinfected by boiling or steaming without material degradation. This ease of cleaning helps pet owners maintain hygienic play conditions for their pets, extending the usable life of the entire chew toy.

1. Customizable design for mass production

We support custom molding for different sizes, shapes and hardness to match specific chew rope designs and pet size categories (small, medium, large). Our precision injection molding process delivers consistent quality across high-volume orders, with stable lead times to meet the production scheduling needs of pet product brands.

1. Weather and temperature resistance

The LSR connector maintains its elasticity and mechanical properties across a wide temperature range (-40℃ to 200℃), making it suitable for pet toys used in outdoor environments, refrigerated storage, or high-temperature disinfection processes. It does not become brittle in cold weather or soft and sticky in high temperatures, ensuring consistent performance in all common usage conditions.

Applications

Our Food-grade LSR Pet Chew Rope Connector is designed as a core connecting component for a wide range of pet interactive chew products, including:

• Large-dog tug-of-war chew ropes: Connects multiple rope ends to form a knotted handle or reinforced center tug point, resisting strong pulling force during interactive play between owners and dogs.
• Dental chew toys: Integrated into multi-component dental rope toys to secure rope sections to rubber chew cores, with a soft surface that massages gums during chewing.
• Interactive treat-dispensing chew toys: Acts as a removable or permanent connector for rope handles attached to treat-dispensing chew bases, combining the benefits of rope play and enrichment feeding.
• Puppy teething toys: The 30-40 Shore A low hardness option provides a gentle, flexible surface for teething puppies to soothe gum discomfort without damaging emerging teeth.
• Outdoor pet toys: The temperature and weather resistance of LSR makes the connector suitable for pet toys designed for backyard, camping or beach use.

All connectors are supplied as finished molded components ready for direct assembly into pet toy products, reducing secondary processing requirements for our customers.

Selection Guide

Hardness Selection

• 30 Shore A – 40 Shore A: Recommended for puppy teething toys and small breed dog chew products, provides maximum softness and gentle biting feel.
• 45 Shore A – 50 Shore A: General purpose option for most medium breed chew ropes, balances softness and structural rigidity for daily interactive play.
• 55 Shore A – 60 Shore A: Recommended for large and extra-large breed tug-of-war ropes, provides higher tensile and tear resistance to withstand strong biting and pulling force.

Size Specifications

We offer standard sizes matching common chew rope diameters, and support full custom dimensional design:

Custom sizes with non-standard inner diameters, outer shapes and connection structures are available per customer drawing requirements.

Material Grade

All our pet chew rope connectors use the same food-grade LSR formulation that meets US FDA and EU food contact safety standards. We do not offer lower-cost non-food grade material for this product category, to ensure consistent compliance with global pet product safety regulations.

Quality Assurance

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

1. Incoming material inspection: Every batch of food-grade LSR raw material is tested for compliance with safety and physical performance standards before entering production.
2. In-process inspection: Dimensional and visual checks are conducted at regular intervals during molding to catch production variations early.
3. Finished product inspection: 100% visual inspection for surface defects, plus random sampling testing for hardness, dimensions and safety parameters before shipment.
4. Full traceability: Every production batch is recorded and labeled, with raw material test reports retained for future reference.

We can provide material safety data sheets (MSDS), certification documents and third-party test reports for regulatory compliance purposes to support our customers’ global market access.
