Food-grade Liquid Silicone Skin-friendly High-elastic Adult Masturbation Cup

Core selling points include 100% food-grade LSR composition that eliminates harmful phthalates, BPA, and heavy metal leaching, a 600% ultimate elongation rate that mimics human tissue elasticity, a non-porous surface that resists bacterial colonization for easy cleaning, and compatibility with all water-based and silicone-based lubricants. The internal texture of the cup is precision-molded with layered ribbed, nubbed, and constriction zones to provide multi-sensory stimulation, while the outer silicone shell offers a non-slip grip even when wet. All production processes adhere to ISO 13485 medical device manufacturing standards, with every unit undergoing post-molding secondary vulcanization to remove residual volatile organic compounds (VOCs) and ensure zero odor during use.

Technical Specifications

Material Properties

This silicone airplane cup uses platinum-cured food-grade LSR as the raw material, with the following key material metrics verified by third-party SGS testing:

Physical Performance

The finished product has been subjected to 10,000+ cycle durability tests to verify long-term functional stability:

• Operating temperature range: -40°C to 220°C, compatible with hot water disinfection (up to 100°C) and low-temperature storage without material deformation
• Surface roughness (Ra): ≤ 0.8 μm, polished seamless surface that prevents lubricant and bodily fluid residue buildup
• Stretch recovery rate: 100% after 200% static stretch held for 72 hours, no permanent deformation
• Fatigue resistance: No cracking, tearing, or texture wear after 10,000 repeated stretch and compression cycles
• Lubricant compatibility: No swelling, discoloration, or material degradation after 72 hours of immersion in water-based, silicone-based, and hybrid lubricants (oil-based lubricants are not recommended, as they may reduce surface finish over extended use)

Process Parameters

The product is manufactured via precision injection molding with strict process control to ensure consistency across every unit:

• Molding temperature: 120°C ± 5°C (upper mold), 115°C ± 5°C (lower mold)
• Curing time: 120 seconds per cycle, fully cross-linked to avoid unreacted monomer residue
• Secondary vulcanization: 2 hours at 180°C in a forced air oven to remove residual low-molecular-weight compounds
• Tolerance control: ±0.1 mm for internal texture dimensions, ±0.5 mm for overall outer dimensions to ensure consistent stimulation and fit
• Post-processing: No chemical coating or surface treatment, all edges are flash-free trimmed via automated CNC cutting to avoid sharp contact points

Product Advantages

1. Industry-leading Skin Safety Profile

Unlike low-cost TPE adult toys that often contain plasticizers and have porous surfaces that harbor bacteria even after cleaning, this food-grade LSR airplane cup is 100% non-toxic, hypoallergenic, and non-porous. It has passed ISO 10993-5 cytotoxicity testing, making it suitable for users with sensitive skin or allergies to common plastic additives. The non-porous surface can be fully disinfected with hot water, alcohol wipes, or toy cleaner, eliminating the risk of bacterial or fungal growth that is common with porous material alternatives.

1. Ultra-realistic Elastic Performance

With a 600% elongation rate and low Shore 00 hardness, the material mimics the softness and stretch of human mucosal tissue far more accurately than harder TPE or PVC blends. The high tear strength of 30 kN/m ensures the internal texture will not tear even during vigorous use, while the 5% compression set means the cup retains its original shape and stimulation intensity for years, unlike lower-quality products that become loose and ineffective after 10-20 uses.

1. Odor-free and Low Maintenance

The platinum curing system and secondary vulcanization process eliminate the characteristic "plastic" or "rubber" odor that plagues many low-cost adult toys. The smooth, non-stick surface requires only simple rinsing with warm water and mild soap after use, with no need for frequent powdering or special maintenance required to keep the material soft. It is also fully waterproof, allowing for use in the shower or bathtub without risk of water damage to the silicone structure.

1. Eco-friendly and Durable Design

LSR is an inert, recyclable material that does not degrade or leach microplastics into the environment during use or disposal, unlike single-use TPE products that are often discarded after a few months of use. This silicone airplane cup has a service life of 5+ years with proper care, reducing waste and long-term cost for users compared to disposable or low-durability alternatives.

Applications

This silicone airplane cup is designed for adult male intimate use, with specific use cases including:

• Personal Pleasure Use: Suitable for solo use by adult users, with three optional hardness grades to accommodate different sensitivity preferences and stimulation needs. The textured internal structure is designed to provide variable intensity stimulation, from gentle to intense, to suit individual preferences.
• Clinical Sexual Health Applications: Recommended by urologists and sex therapists for patients with premature ejaculation, erectile dysfunction, or difficulty achieving orgasm, as the adjustable stimulation intensity and consistent material properties allow for controlled desensitization training and performance practice.
• Long-distance Relationship Use: Compatible with most universal automatic stroker mounts and app-controlled motorized bases, allowing for remote partner control and synchronized intimate experiences for couples separated by distance.
• Adult Entertainment Venue Use: Suitable for use in high-end adult wellness centers and clubs, as the easy disinfection and non-porous surface allow for safe multi-user use when paired with disposable protective liners.

Application note: Always use a compatible lubricant to reduce friction and avoid material wear. Disinfect the product before and after each use, and store it in a cool, dry place away from direct sunlight and contact with other rubber or plastic products to avoid cross-contamination.

Selection Guide

Hardness Selection

• Shore 00-10 (Extra Soft): Recommended for first-time users, users with high sensitivity, or those seeking a ultra-realistic, soft tissue-like experience. Provides gentle stimulation with minimal friction, ideal for extended use sessions.
• Shore 00-20 (Medium Soft): The most popular universal option, balances softness and structural support to deliver targeted stimulation from the internal texture without being overly harsh. Suitable for most users with average sensitivity.
• Shore 00-30 (Firm): Recommended for experienced users or those seeking higher intensity stimulation. The firmer material provides more pronounced pressure from the internal rib and nub textures, ideal for users with lower sensitivity.

Size Specifications

Quality Assurance

Every silicone airplane cup undergoes a rigorous 5-step quality control process before leaving the factory:

1. Raw Material Inspection: Every batch of LSR is tested for hardness, tensile strength, and heavy metal content to ensure compliance with food-grade standards.
2. In-process Molding Inspection: 100% of units are inspected for dimensional accuracy, flash defects, and surface blemishes immediately after molding.
3. Performance Testing: Random samples from each production batch are subjected to stretch cycle tests, disinfection resistance tests, and lubricant compatibility tests to verify long-term durability.
4. Post-vulcanization Inspection: All units are inspected for odor and residual VOC content, with any units with detectable odor rejected.
5. Final Packaging Inspection: Every unit is visually inspected for defects, sealed in food-grade plastic packaging, and labeled with production batch number and expiration date (10 years from manufacture).

All products are certified by FDA (food contact), CE (EU safety), RoHS (hazardous substance restriction), and REACH (EU chemical regulation). We offer a 2-year free replacement warranty for all manufacturing defects, including material tearing, deformation, and abnormal odor, with a 30-day no-questions-asked return policy for unopened products. For bulk orders, we provide full batch test reports and custom certification support to meet regional regulatory requirements.
