The core application scenario of the ozone aging chamber focuses on the ozone aging resistance performance testing of polymer materials (rubber, plastic, coatings, seals, etc.), covering multiple industries with high requirements for material durability and safety. The core is to simulate the erosion of materials by ozone in the natural environment, evaluate the reliability of products in the long term, and avoid problems such as cracking and failure caused by ozone aging. The following are specific segmented application scenarios:

1Core application areas:

Rubber materials (especially vulcanized rubber containing unsaturated bonds) in the rubber industry (the most mainstream scenario) are sensitive to ozone, and even trace amounts of ozone can cause surface cracking, making them the main test objects for ozone aging chambers:

1Tire manufacturing industry：

（1）Test objects: tire sidewall rubber, tread rubber, bead sealant, valve rubber parts

（2）Test purpose: To evaluate the anti ozone cracking ability of tires during outdoor driving (especially in high-speed and high-temperature environments), avoid safety hazards such as sidewall cracking and air leakage, and ensure the service life of tires (such as truck and bus tires that need to withstand long-term outdoor exposure and ozone erosion)

（3）Typical requirement: Dynamic tensile testing (simulating tire deformation during driving), observing the number and length of cracks after accelerated aging

2Sealing/Rubber Products Industry

（1）Test objects: O-rings, door and window sealing strips, pipe seals, hydraulic seals, pneumatic seals

（2）Test purpose: To verify the ozone resistance performance of seals under dynamic (such as mechanical motion, pressure changes) or static working conditions, and to avoid leakage caused by seal failure (such as industrial equipment hydraulic system seals, building door and window sealing strips)

（3）Key scenarios: Automotive seals (doors, windows, engine compartment), industrial machinery seals, household appliances (refrigerators, air conditioners) seals

3Rubber hoses/tapes/shock-absorbing products

（1）Test objects: Industrial conveyor hoses (oil, gas, water), transmission tapes (V-belts, synchronous belts), rubber shock absorbers, rubber foot pads

（2）Test purpose: to ensure the anti-aging ability of the product in outdoor or harsh environment (such as mining machinery, engineering machinery), and to avoid hose cracking and leakage, belt breakage, and shock pad failure

4Shoe material industry

（1）Test objects: sole rubber, upper sealant, sports shoe air cushion seal

（2）Test objective: To evaluate the aging resistance of footwear in daily wear (exposure to atmospheric ozone), in order to prevent sole cracking and shoe upper delamination

2、 Automobile and transportation industry

Outdoor components of transportation vehicles such as cars and high-speed trains need to withstand ozone, ultraviolet radiation, and temperature changes for a long time, which is an important application scenario for ozone aging chambers:

1auto parts

（1）Test objects: wiper rubber strip, window lifting seal, engine peripheral rubber parts (water pipes, oil pipe joints), chassis shock absorber rubber, wire harness protective cover, air conditioning pipeline seal

（2）Test objective: To simulate the outdoor usage environment of vehicles in different climates (cold in the north, humid and high temperature in the south), ensuring that components do not crack or harden within 3-5 years, avoiding water leakage, abnormal noise, and functional failure (such as unclear wiping after the wiper rubber strip ages)

2Rail Transit/Aerospace

（1）Test objects: high-speed rail door seals, shock-absorbing rubber pads, cable sheaths, aircraft cabin seals, aviation rubber conduits

（2）Test objective: To meet high reliability requirements, simulate ozone environments at high altitudes (aircraft) and outdoor tracks (high-speed rail), and avoid seal failure (such as cabin pressure leakage) and cable insulation aging and damage

IIIWire and cable industry

The insulation sheath of wires and cables is mostly made of rubber or plastic material, which is prone to ozone corrosion and aging cracking during outdoor use, causing safety hazards:

（1）Test objects: power cable insulation sheath (especially outdoor cables, overhead cables), communication cable sheath, new energy cable (photovoltaic, wind power) sheath, automotive wire harness insulation layer

（2）Test purpose: To evaluate the ozone resistance performance of cables in long-term outdoor use (such as outdoor laying and high-altitude installation), prevent insulation layer cracking, leakage, and short circuit, and ensure the safety of power/signal transmission

（3）Key scenarios: High voltage transmission and transformation cables, cables for new energy power plants (photovoltaic, wind power), rail transit cables, ship cables (dual erosion of marine environment and ozone)

4Construction and building materials industry

Polymer materials in building materials need to withstand long-term outdoor exposure, and ozone aging is one of the important aging factors:

（1）Test objects: Building waterproofing membranes (rubber), building sealants (silicone, polyurethane), curtain wall seals, rubber floor tiles, outdoor plastic track materials, door and window sealing strips

（2）Test purpose: To ensure that the materials do not crack or fall off during the service life of the building (usually more than 20 years), and to ensure the waterproof and sealing performance of the building (such as waterproof membrane aging and cracking leading to water leakage, sealant aging leading to air leakage from doors and windows)

5new energy industry

New energy equipment (photovoltaic, wind power, energy storage) is mostly deployed outdoors, and components need to withstand environmental and ozone aging:

（1）Test objects: photovoltaic module sealant (EVA film peripheral sealing), wind turbine blade rubber connectors, energy storage battery box seals, charging pile cable sheaths

（2）Test purpose: To avoid sealing failure caused by long-term outdoor exposure (such as water ingress and short circuit of photovoltaic modules), cable aging and damage, and to ensure the long-term stable operation of new energy equipment (usually requiring a lifespan of more than 25 years)
