Question PLastic, rubber and UV sunlight
« on: April 15, 2021, 09:44:31 AM »
I have a PS2 Slim 90000 and its case is ABS plastic and it has rubber parts, this device is located on a wooden table, the lights with UV in my house and the sunlight coming into the house will dry out, crack and damage the ABS plastic and the rubber of this device? my house uses LED bulb

Because ABS has an aromatic group it has a pretty poor UV stability. So the general answer is yes, UV light can degrade the performance of your case. Hard to be more specific because of many factors, including thickness, grade of ABS, additives in the plastic, color, type and intensity of light, etc etc.

1) did you see the pictures i posted?

2) there is a difference between UV from indirect sunlight entering the house and UV from direct sunlight both dry out and make brittle ABS plastic and PS2 console rubber and CRT TV?

3)if I put on top of these devices fabric or cotton flannel protects from UV rays from indirect sunlight or the UV penetrates and attracts the ABS plastic and rubber, what recommendation? i use devices alternative moments

1. No I cannot access those from this computer.

2. Yes, indirect sunlight will be different from direct sunlight. You windows may have UV coating on them. "Indirect" also leaves a lot of room for interpretation - how reflective are your walls, etc. Impossible to guess. But regular ambient room light or indirect sunlight will not rapidly regrade your devices.

3. Cover your devices with fabric if it makes you feel better. It can't hurt. You may or may not notice a difference.

I need to find out if any fabric and cotton flannel blocks UV from penetrating and accessing plastic and rubber or passes through the pores

sunlight is everywhere whether direct or indirect sunlight inside the house or reflective on the walls but I don't know the UV they have for the soon term damaging plastics and rubber so I thank you for the answers

Only way to know how much light passes through a fabric is to measure using a light meter that is sensitive to your wavelength of interest. Even then, it'll just be a number that needs a lot of context to interpret. The issue isn't whether UV light can pass through fabric and damage a material underneath, but how much passes through as a function of time, what the acceptable damage threshold is, and so forth. Those aren't easy things to define. You are seeking a yes or no answer to a question that is not a yes or no question. This needs to be approached as a risk assessment.

Cotton fabrics are pretty decent UV absorbers, and some even have SPF ratings.

If you really want to minimize the risk to your devices, I'd go with one of those.

Does any cotton fabric provide any UV protection for ABS plastic and rubber? is keeping on the appliances a good idea?

I don't have any tool to measure UV so I ask for your help and experience on this subject about the UV of sunlight that enters the homes to dry out plastic and rubber
