Food-Grade Silicone Tube

Silicone phone cases are protective accessories made of high-purity solid or modified silicone through high-temperature vulcanization and precision molding. They fit the phone contour, with reserved openings for cameras, buttons and ports, and some have lanyard holes or brackets. Core functions: ① Anti-drop and shock resistance, absorbing impact to protect the phone; ② Scratch and stain resistance, blocking dust, fingerprints and scratches; ③ Comfortable holding and decoration, non-slip, skin-friendly and diverse in style. Suitable for all smartphone users.

Ordinary Silicone Cases: Standard formula, moderate softness, affordable, providing basic protection, suitable for entry-level users.
Anti-drop Thickened Cases: Thickened (1.0-1.5mm) with reinforced corners/airbag buffer, strong impact resistance, suitable for outdoor enthusiasts or users prone to dropping phones.
Functional Silicone Cases: Added with brackets, lanyard holes, waterproof or heat dissipation functions, suitable for users with specific needs.
High-end Custom Cases: High-purity silicone, precision craftsmanship, fine texture and perfect fit, suitable for high-end smartphones, higher-priced.

High-purity Medical Silicone: Non-toxic, elastic, skin-friendly, temperature range -40℃ to 200℃, anti-aging and anti-yellowing, for high-end cases.
Ordinary Synthetic Silicone: Low purity, low cost, poor softness, easy to age and crack, suitable for short-term use.
Liquid Silicone: Softer, more delicate, anti-drop, anti-fingerprint and anti-yellowing, mainstream medium-high-end raw material.
Modified Silicone: With wear-resistant, anti-yellowing or heat-dissipating additives, for functional cases.
High-quality cases are soft, odorless and quick to rebound; inferior ones are rough, smelly, easy to age and may irritate the skin.

Yellowing/discoloration: Sun oxidation, contact with sweat, oil, cosmetics or inferior pigments.
Hardening/cracking: Material aging, high temperature, frequent stretching, scratches or organic solvent contact.
Stickiness/dusting: Silicone characteristics or failure to clean sweat and oil in time.
Looseness: Stretching deformation, edge wear or improper installation/disassembly.

Cleaning: Wipe daily with a soft cloth; deep clean weekly with warm water and neutral detergent; remove slight yellowing with white vinegar or toothpaste; avoid organic solvents.
Maintenance: Avoid sunlight and high temperature; install/disassemble gently; replace if damaged or loose; store in a dry place when not in use.

Fit: Choose the correct phone brand and model for precise openings and perfect fit.
Material: Select according to usage needs (e.g., liquid silicone for anti-yellowing).
Quality: Choose regular brands to avoid inferior cases that irritate the skin.

Silicone phone cases are mainstream phone protectors with anti-drop, softness, water/stain resistance and high cost-performance. Mastering cleaning and maintenance methods and choosing suitable cases can extend service life, effectively protect phones, and improve holding comfort and decorativeness.
