Ruixiang Food-Grade Silicone Tubing: Safeguarding Global Food Industry
> In a Class 10,000 cleanroom in Liaobu Town, Dongguan, a transparent silicone tube with an inner diameter of merely 0.14mm undergoes final inspection before shipping to a European infant formula factory – embarking on its mission to protect millions of family dining tables worldwide.
Established in 2012, **Dongguan Ruixiang Precision Silicone Products Co., Ltd.** has refined food-grade silicone tubing technology to industry-leading standards through its core philosophy of "**Professionalism, Precision, Innovation**".
Operating under ISO 13485 Medical Device Quality Management Systems and Class 10,000 cleanroom environments, Ruixiang's silicone tubes have become designated components for global brands like Nestlé and Philips, redefining safety benchmarks for food-contact materials.

## I. Technological Foundation: Revolutionary Platinum-Catalyzed Curing
### 1. Molecular-Level Purity Assurance
While traditional peroxide-cured silicone tubes often retain sulfurous odors, Ruixiang's **platinum-catalyzed crosslinking technology** enables precise siloxane bonding at 150°C, eliminating byproduct residues entirely. This breakthrough achieves:
- **Zero-Emission Compliance**: Passes FDA 21 CFR 177.2600 migration tests with undetectable heavy metals/VOCs
- **Optical-Grade Clarity**: >92% light transmittance for liquid flow visibility comparable to glass
- **Permanent Anti-Yellowing**: Yellow Index (YI) remains <1.5 after 500-hour QUV UV accelerated aging
### 2. Micron-Level Precision Control
Within Ruixiang's GMP cleanrooms, tubing manufacturing achieves microscopic precision:
- **Ultra-Thin Walls**: 0.1mm thickness with ≤±5% uniformity deviation
- **Sub-Hair Tolerances**: ±0.02mm dimensional accuracy (1/4 human hair diameter)
- **Complex Co-Extrusion**: Single-process production of dual/triple-lumen tubes for segregated delivery

## II. Performance Excellence: Unyielding Protection in Extreme Environments
### 1. Physics-Defying Mechanical Properties
*Table: Core Performance Comparison vs. Conventional Materials*
| **Parameter** | **Ruixiang Silicone Tube** | **Standard Rubber Tube** | **Test Standard** |
|------------------------|----------------------------|--------------------------|-------------------|
| Temperature Resistance | -60℃~250℃ | -20℃~120℃ | ASTM D2671 |
| Tensile Strength | 8.5-25 MPa | 3-8 MPa | ISO 37 |
| Compression Set | ≤5% (200℃×22h) | ≥30% | ASTM D395 |
| Kink Recovery Time | <0.5s (360° twist) | >2s | Internal Standard |
These properties stem from synergistic effects of **Germany's Wacker fumed silica** and **Japan's Shin-Etsu chain modifiers**, maintaining ±3% flow accuracy after 100,000 peristaltic pump compressions.
### 2. Absolute Safety Through Chemical Inertness
Ruixiang tubes demonstrate exceptional stability when handling pH 2.8 citric acid concentrate:
- **Non-Adherent Surface**: Zero residue from ≥65°Bx syrups, reducing microbial risk by 90%
- **Oil Resistance**: <3% volume expansion after 168h in 120℃ palm oil
- **Medical-Grade Cleanliness**: USP Class VI compliant with Grade 0 cytotoxicity
