Why Do Male Strokers Leak Oil and Crack？A Material Breakdown

Problem: For years, users complained about sticky surfaces, oily residues, and premature cracks in male strokers.
These issues not only reduce pleasure but raise hygiene concerns and force frequent replacements.
Solution: Through rigorous R&D, our factory replaced porous TPE with medical-grade silicone—creating softer, oil-free strokers that last 3x longer without splitting.
What Causes Oil Leakage and Cracking in Male Strokers?
The core issue lies in material science. Traditional Thermoplastic Elastomers (TPE) contain plasticizers that migrate to the surface ("oozing oil") and evaporate over time, leaving the material brittle and prone to cracks. Medical silicone, however, is a non-porous, platinum-cured polymer with cross-linked molecules. This structure eliminates oil additives, resists tearing, and maintains elasticity through hundreds of uses.Keep reading to discover:

Answering Top Consumer Questions About Male Stroker Materials
1. Why Do TPE-Based Strokers Degenerate So Quickly?
TPE relies on petroleum-derived plasticizers (up to 30% of its composition) to achieve softness. These oils gradually seep out ("sweating"), causing:Surface stickiness that attracts dust and microbes
Material shrinkage as plasticizers evaporate
Micro-cracks from repeated stretching of weakened TPE
Lab tests show TPE strokers lose 40% flexibility after 50 washes.
2. How Does Medical Silicone Prevent Oil Leaks and Splits?
Medical silicone’s advantages stem from its manufacturing:| Property | TPE | Medical Silicone |
|---|---|---|
| Porosity | High (traps bacteria) | Non-porous (hygienic) |
| Plasticizers | Yes (oils leak out) | None (chemically stable) |
| Tear Resistance | Low (develops splits) | High (withstands 500% stretch) |
| Longevity | 3-6 months | 2+ years with proper care |
The FDA-compliant material also withstands boiling water sterilization—critical for preventing bacterial growth.
3. What Makes a Silicone Stroker "Premium Quality"?
Look for these markers:Shore Hardness 00-30: Measures softness. Our strokers use 00-20 silicone (skin-like feel) vs. cheaper 00-40 blends.
Platinum Cure Process: Avoids peroxide-cured silicones that may leave toxic residues.
ISO 10993 Certification: Proves biocompatibility for repeated intimate contact.
Seamless Mold Design: Eliminates weak points where cracks often start.
4. Why Pay More for Silicone Over TPE?
While silicone strokers cost 2-3x more upfront, they save money long-term:No replacements: Lasts 5x longer than TPE (our lab-tested lifespan: 2.5 years)
Lower maintenance: Dishwasher-safe; no cornstarch needed to prevent stickiness
Health safety: Zero risks of phthalate exposure from leaked oils
Conclusion: Material Innovation Solves the Oil-and-Crack Dilemma
Switching from unstable TPE to medical silicone transforms male strokers into durable, hygienic investments—not disposable novelties. By prioritizing material science over cheap shortcuts, manufacturers can finally deliver what users truly want: products that feel better, last longer, and respect their health.
